Subject: [PATCH] fix: stop root releases from changing package versions and
 tag single-package release PRs

- The root package (path ".") python strategy changes the version string
  in every version.py file in the repository. The 1.8.2 and 1.8.3
  releases wrote the LoopStructural version into the map2loop and
  loopstructural_visualisation version.py files, and
  loopstructuralvisualisation was published as 1.8.2. The version.py
  files now read the version from the package metadata, and
  loopstructural_visualisation sets its version (0.2.0) in pyproject.toml.
- With one combined release PR, a PR that holds only the root package is
  not tagged ("PR component: undefined does not match configured
  component"), which blocked all later releases. Use separate release
  PRs for each package.
- The root path outputs of release-please-action have no "<path>--"
  prefix, so LoopStructural--release_created was never set and the conda
  and documentation builds did not start.
