[FEAT] SVN support

[mike1936]

Is your feature request related to a problem? Please describe

I have some historical repositories that are maintained in SVN, need to come back to those repositories time to time and try to use conventional commits to compose an organized commit messages. Currently, my process involves opening a random Git repository to draft the commit messages, then copying them back into the message input box of the SVN project. I am wondering if there are any considerations of adaptation of the extension to enable the functionality directly within SVN-controlled repositories, streamlining the commit message composition progress.

Describe the solution you'd like

It would be highly beneficial if we could enable the composition of commit messages directly within SVN-controlled repositories through a Conventional Commit command search.
