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:

```

            ^~~~~
            auto *
```

* .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'
```
