Add "ZS" to the file manager's name to allow for differentiation

[Jevil7452]

At this moment, if you have both 7-Zip (normal) and 7-Zip ZSTD installed, it can be confusing to know which one is which

With this PR, the names are different, so it's easier to know which one is which

This PR also changes the names used in the Start menu

(To whoever decides to accept this PR, please ignore the "Update build-win.yml" commits, that was me trying to get Github Actions to work)

Thank you, I have added this pr.
Why should workflow_dispatch also be triggered?

[Jevil7452]

The reason why I added workflow_dispatch to the Github Actions files was because I was trying to run Github Actions manually, to test out my code changes, as I couldn't get the code to compile on my PC, but I didn't see a run workflow button, so I looked up online how to get it, and the results i found said to add workflow_dispatch, so I did, however it would've been better to just enable Github Actions before pushing my commit related to changing the file manager's name. I apologize for these unneeded commits.

No need for apologizing - everything is fine ;-)
Thanks for you pull request and the next release will have this applied.
