Add version bumping in uv.lock and make dev versions PEP440 compliant

[juhoinkinen]

Reasons for creating this PR

The bumpversion config did not take the version string in uv.lock into account, and running uv sync after the release, a git diff in uv.lock was introduced:

-version = "0.1.0.dev0"
+version = "0.2.0.dev0"

Note that uv normalized the version from 0.2.0-dev given in pyproject.toml.
