Change references and bump dependencies

[wcmjunior]

This PR contains the following changes:

• Bump golang to 1.22
• Bump all the dependencies to the latest available versions
• Improve docs readability and add a disclaimer about the reason for this fork
• Add Dependabot
• Changes the default branch to main to follow conventions of all our other branches (sole reason)
• Get CI to work

I think large scale changes in this PR (formatting, change in import path in go files etc) will make it really tough to merge any future upstream changes (even though we don't expect a lot of those). My suggestion would be to not touch the go files at all (except where we make the functionality change).

The import path change should be achieved using replace directives in the respective go.mod files rather than changing the .go files themselves.

LGTM - please check the minor comment for the Dockerfile. I presume this builds correctly and you tested a sample run as well?
