Python-semantic-release

Fix

* fix(cli-version): change implementation to only push the tag we generated

Restricts the git push command to only push the explicit tag we created
which will eliminate the possibility of pushing another tag that could
cause an error.

Resolves: 803 ([`8a9da4f`](https://github.com/python-semantic-release/python-semantic-release/commit/8a9da4feb8753e3ab9ea752afa25decd2047675a))

* fix(algorithm): handle merge-base errors gracefully

Merge-base errors generally occur from a shallow clone that is
primarily used by CI environments and will cause PSR to explode
prior to this change. Now it exits with an appropriate error.

Resolves: 724 ([`4c998b7`](https://github.com/python-semantic-release/python-semantic-release/commit/4c998b77a3fe5e12783d1ab2d47789a10b83f247))

Performance

* perf(algorithm): simplify logs & use lookup when searching for commit & tag match ([`3690b95`](https://github.com/python-semantic-release/python-semantic-release/commit/3690b9511de633ab38083de4d2505b6d05853346))

Feature

* feat(cmd-version): changelog available to bundle (779)

* test(util): fix overlooked file differences in folder comparison

* test(version): tracked changelog as changed file on version create

Removes the temporary release_notes hack to prevent CHANGELOG generation on
execution of version command. Now that it is implemented we can remove the
fixture to properly pass the tests.

* feat(cmd-version): create changelog prior to build enabling doc bundling ([`37fdb28`](https://github.com/python-semantic-release/python-semantic-release/commit/37fdb28e0eb886d682b5dea4cc83a7c98a099422))

Fix

* fix(cli): enable subcommand help even if config is invalid

Refactors configuration loading to use lazy loading by subcommands
triggered by the property access of the runtime_ctx object. Resolves
the issues when running `--help` on subcommands when a configuration
is invalid
