Fix scripts to run under uv correctly

Description (What does it do?)

The scripts weren't working for me with the usages in the readme and I initially missed the gotcha at the top. I initially implemented things this way when the tooling we used made this easier. Under uv isn't not exactly clear if/how we can get the ergonomics to work well so I just moved everything into a scripts/ folder for simpler usage.

How can this be tested?

Run some commands to be sure they still work:

• uv run scripts/changelog.py list -a common
• uv run scripts/version.py show --app common
• uv run scripts/release.py create --help - can't actually run a release so this just verifies the command loads correctly

Functionality looks fine to me.

I had issues running commands via uv locally - it turned out I needed to be in the src/ folder to run them. Once i did that, everything worked OK to the extent that I could test it. This was on both macOS and Ubuntu. Can the docs note this? (FWIW, the Docker env worked as expected, and worked running the scripts from within the src/ folder too.)

You shouldn't need to be in src/ to run them, what error were you getting?

Looks like I need to fix up historical changelogs, not sure why those never got consumed and why previous PRs never failed them.

If I'm not in src/ it doesn't see any apps to work with (but only locally). Example:

$ uv run -p 3.11 scripts/version.py show --help
Usage: version.py show [OPTIONS]

  Show current version of your project.

Options:
  -v, --verbose                 Control log level. -vv for debug level.
  -f, --fetch / -n, --no-fetch  Sync tags from remote origin.
  --environ                     Print version state for use with shell
                                scripts: eval $(bumpver show --environ)
  -a, --app []                  [required]
  --help                        Show this message and exit.

From src/ I get apps listed.
