Settings could not be read from \\wsl$

A few follow up from #9702

Proposed changes

A few a follow up related to WSL Git.

• Settings could not be read from \wsl$

The URI is invalid, why the path has to be read with a StreamReader.
This caused various issues like remotes could not be disabled

This is not related to WSL Git, it also occurs if Windows Git is used.
This is one reason why insiders Windows builds also supports wsl.localhost
(\wsl$ paths will be required to utilize wsl git. This is a feature but must be documented.)

This problem was primarily seen when deactivating remotes, an exception occurred (as a settings file were not refreshed).

• WSL: Remotes for filepaths could not be saved

Paths must be manipulated to match Git executable.

• WSL: Git internal paths were incorrectly resolved

Affected Remote mostly

• WSL: force-push was inserted incorrectly

The --force-with-lease offered if a push is refused assumed that the command started with "push".
The option is "inserted" in the command string.
WSL Git has the distribution first, why the insert point differs.

Note: The output from git push is not always available for WSL Git (for instance at home).
At work it works though.

Test methodology
