High Semgrep LSP CPU usage caused by recurring Git operations

[tomasf-stripe]

Describe the bug
When using the Semgrep LSP in large Git repositories that have many contributors (>1,000) and files, the Git operations that are ran by the LSP cause some very high CPU usage spikes every few seconds.

To Reproduce
Run the LSP and observing the CPU usage in a very large repo.
Expected behavior
If only_git_dirty is set to false in the LSP settings, I'd expect that no Git operations would be run by the LSP which would resolve this issue.
