Aligns Deno's `server.address()` with Node.js v18.4.0+ behavior by
returning the `family` property as a string ("IPv4" or "IPv6") rather
than a number.

Node.js briefly changed `family` from string to number in v18.0.0
(nodejs/node#41431), but reverted in v18.4.0 (nodejs/node#43054) due
to ecosystem breakage (nodejs/node#43014).

This fix ensures compatibility with npm packages that rely on the
string format, which has been the stable API since Node.js v18.4.0.

Aligns Deno's Node.js compatibility layer with Node.js v18.4.0+ behavior
by returning the `family` property as a string ("IPv4" or "IPv6") rather
than a number in `server.address()` and socket address methods.

Node.js briefly changed `family` from string to number in v18.0.0
(nodejs/node#41431), but reverted in v18.4.0 (nodejs/node#43054) due to
ecosystem breakage (nodejs/node#43014).

Changes:
- `http.Server.address()`, `https.Server.address()`, `http2.Server.address()`
  now include `family` property as string
- `net.Server.address()` returns string `family` via tcp_wrap.ts
- `socket.remoteFamily` returns string instead of number
- `dns.lookup()` accepts both numeric (0, 4, 6) and string ("IPv4", "IPv6")
  family values, matching Node.js behavior

Family value derivation follows Node.js C++ implementation:
- isIP() === 4 → "IPv4"
- isIP() === 6 → "IPv6"
- isIP() === 0 → undefined (defensive, matches Node.js behavior for
  non-IP addresses, though not practically reachable via TCP server APIs)

## Summary

Aligns Deno's Node.js compatibility layer (`node:net`, `node:http`,
`node:https`,
`node:http2`, `node:dns`) with Node.js v18.4.0+ behavior by returning
the `family`
property as a string (`"IPv4"` or `"IPv6"`) rather than a number in
`server.address()`
   and socket address methods.

Node.js briefly changed `family` from string to number in v18.0.0
(nodejs/node#41431),
   but reverted in v18.4.0 (nodejs/node#43054) due to ecosystem breakage
   (nodejs/node#43014).

This fix ensures compatibility with npm packages that rely on the string
format, which
   has been the stable API since Node.js v18.4.0.

   ## Changes

- Modified `ext/node/polyfills/http.ts` to add `family` property to
`address()` return
- Modified `ext/node/polyfills/internal_binding/tcp_wrap.ts` to return
string `family`
instead of number in `getsockname()`, `getpeername()`, and `#connect()`
- Modified `ext/node/polyfills/net.ts` to fix `socket.remoteFamily`
getter (no longer
   needs conversion since `family` is now a string)
   - Modified `ext/node/polyfills/dns.ts` and
`ext/node/polyfills/internal/dns/promises.ts` to accept string family
values (`"IPv4"`,
`"IPv6"`) in `lookup()`, matching [Node.js
behavior](https://nodejs.org/api/dns.html#dnslookuphostname-options-callback)
- Added tests in `tests/unit_node/http_test.ts`,
`tests/unit_node/http2_test.ts`,
   `tests/unit_node/https_test.ts`, `tests/unit_node/dns_test.ts`, and
   `tests/unit_node/net_test.ts`

   ## Node.js Compatibility Note

For non-IP addresses (when `isIP()` returns 0), the `family` property is
`undefined`.
This matches Node.js C++ behavior in
[`AddressToJS`](https://github.com/nodejs/node/blob/main/src/tcp_wrap.cc)
where family
is only set for `AF_INET` (`"IPv4"`) and `AF_INET6` (`"IPv6"`), and left
undefined
   otherwise.

  Examples of bad title:
    - fix #7123
    - update docs
    - fix bugs

2. Ensure there is a related issue and it is referenced in the PR text.
3. Ensure there are tests that cover the changes.
4. Ensure `cargo test` passes.
5. Ensure `./tools/format.js` passes without changing files.
6. Ensure `./tools/lint.js` passes.
7. Open as a draft PR if your work is still in progress. The CI won't
run
   all steps, but you can add '[ci]' to a commit message to force it to.
