Add bumpver and fix pypi publish

[bofh69]

bumpver is now used to update the versions and tag a new release, using semantic versioning formatted tags in the future.

README.md's links are updated by the workflow job before building to link to github's tag tree for the new tag.

The sed command references $BASE_URL but it won't be expanded correctly due to the assignment error on the previous line. Additionally, the regex pattern appears to be attempting to match markdown links but may not work as intended. The pattern should likely be s#](\\([^h][^)]*\\))#]($BASE_URL/\\1)#g to properly match relative links and avoid matching links that start with 'h' (like http/https).

Suggested change

	BASE_URL = "https://github.com/bofh69/PN5180-tagomatic/tree/$VERSION"
	sed -i "s#](\\([^h]\\)#$BASE_URL/\\1#" README.md
	BASE_URL="https://github.com/bofh69/PN5180-tagomatic/tree/$VERSION"
	sed -i 's#](\([^h][^)]*\))#]('"$BASE_URL"'/\1)#g' README.md
