feat: remove Python 3.7 support (#5191)
* First pass updating misc files, informed by https://github.com/pybind/pybind11/pull/5177/commits
* Remove jobs using silkeh/clang and gcc docker containers that come with Python 3.7
* Add silkeh/clang:17-bookworm
* Add job using GCC 7
* Revert "Add job using GCC 7"
This reverts commit 518515a761.
* Try running in ubuntu-18.04 container under ubuntu-latest (to get GCC 7)
* Fix `-` vs `:` mixup.
* This reverts commit b1c4304475.
Revert "Try running in ubuntu:18.04 container under ubuntu-latest (to get GCC 7)"
This reverts commit b203a294bb.
* `git grep 0x03080000` cleanup.
* `git grep -I -E '3\.7'` cleanup.
Removes two changes made under pybind/pybind11#3702
* Revert "`git grep -I -E '3\.7'` cleanup."
This reverts commit bb5b9d187b.
* Remove comments that are evidently incorrect:

```
* .github/workflows/configure.yml: Change from Python 3.7 to 3.8
* Misc cleanup pass
* Miscellaneous changes based on manual review of the `git grep` matches below:
```
git_grep_37_38.sh |& sort | uniq -c
```
With git_grep_37_38.sh:
```
set -x
git grep 0x0307
git grep 0x0308
git grep PY_MINOR_VERSION
git grep PYPY_VERSION
git grep -I -E '3\.7'
git grep -I -E '3\.8'
git grep -I -E '\(3, 7'
git grep -I -E '\(3, 8'
git grep -I -E '3[^A-Za-z0-9.]+7'
git grep -I -E '3[^A-Za-z0-9.]+8'
```
