chore(build): publish vscode extension when changed

[fynnfluegge]

Skips step Publish Extension to Visual Studio Marketplace in publish job if no changes made to VS Code extension. Adds step to fetch commit SHA of last successful workflow. The previous reverted solution missed to handle commits with failed jobs, in particular if there is new commit with cli changes once before the last one has finished and hence cancelled. That means it should always taken the diff against the lastest successful commit in account.

Closes #2672.

Hey @MarkMcCulloh second try here, since I saw an issue in the initial approach.
I added a step to the workflow to fetch the commit SHA of the last successful commit. The initial approach just calculated git diff against the previous commit which is not always correct since the workflow of that commit was cancelled or failed. I tested this here by switching the main branch to the-wing-trinity since there are several workflow failures and it gave me the correct SHA of the last successful commit which is 15ae922.
I think this approach seems promising now.
