It seems that using /proc/1/cgroup is now broken to detect docker. Other projects have been using /proc/1/mountinfo instead (see pre-commit/pre-commit#3535)

This MR contains the following updates:

| Package | Update | Change |
|---|---|---|
| [pre-commit](https://github.com/pre-commit/pre-commit) | minor | `4.3.0` -> `4.4.0` |

MR created with the help of [el-capitano/tools/renovate-bot](https://gitlab.com/el-capitano/tools/renovate-bot).

**Proposed changes to behavior should be submitted there as MRs.**
