fix: Allow commiting of files large than 100mb if handled by LFS

[TimonGisler]

The plugin refuses to add files bigger than 100mb if the remote is github, even if an file is handled by LFS.

I added some logic that checks if a file is (or will be) handled by LFS, before blocking the commit.

Detailed Problem Description
Commit Where Check for Too Big Files Was Added

I have not yet implemented IsomorphicGit, but I am happy to do that if I get feedback on whether my change is being considered.
The changes were only tested on my Windows 11 machine (not on Linux or macOS).

This is my first ever PR to an open source project, so any feedback is welcome. I would be very happy if this actually were merged. :D

Thanks for this pr! Just some comments about a bit of different structure, and you will need to fix the formatting with prettier.

Thanks for the fixes. I just noticed that you are currently passing the vault_path to the git lfs check, but it needs the repo relative path, which is currently not stored in those objects. So it needs a bit more of restructure, which I will add to this pr in the next days.
