Fails if git config item `core.fsmonitor` is enabled

[timja]

Noticed in: Azure/terraform-azurerm-avm-res-dbforpostgresql-flexibleserver#72

I have git fsmonitor enabled on my machine to improve performance of git.

./avm pr-check fails with it enabled:

lstat /src/.git/fsmonitor--daemon.ipc: no such file or directory

Relevant log:

To work around it I:

• Temporarily disabled it in my git config file
• Stopped all running daemons:pkill git
• Removed the local folder that it was tripping up on: rm -rf .git/fsmonitor--daemon*
