feat: Add GitHub actions

[hanjano]

• python-semantic-release releases version that is not commited in the repo yet
• to circumvent this, it's required to commit version update + delete and add version tag
• the build & release process of python-semantic-release is not needed
• and all this package basically does is find previous tag + increment based on feat/fix/refactor in the commit after the tag, which likely could be replaced with 4 lines of bash script
• also I guess I'd prefer version to be updated as part of squash + merge from feature branch [pre-merge action / hook?]

Note: After merging, version will update to 0.2.0 and release will be attempted (but is disabled), after requires token to be configured and enabled
