Added missing quotes in WSL instructions

One of the commands for WSL configuration was missing quotes which resulted in invalid configuration.

One of the commands for WSL configuration was missing quotes which resulted in invalid configuration.

The space in "Program Files" is guarded by a slash (\), so I don't see how this was a problem before.

However, using quotes is more idiomatic.

With the " I guess we don't still need the \ before the space?

[nimatt]

Actually both are required. When using only \ it does not get persisted in the git config

$ git config --global credential.helper /mnt/c/Program\ Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe
$ git config --global -l
credential.helper=/mnt/c/Program Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe
...
$ git fetch
/mnt/c/Program Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe get: 1: /mnt/c/Program: not found
...

Using only " will have the same result

$ git config --global credential.helper "/mnt/c/Program Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe"
$ git config --global -l
credential.helper=/mnt/c/Program Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe
...
$ git fetch
/mnt/c/Program Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe get: 1: /mnt/c/Program: not found
...

Only when using both we end up with the \ in the config and it starts working

$ git config --global credential.helper "/mnt/c/Program\ Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe"
$ git config --global -l
credential.helper=/mnt/c/Program\ Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe
...

Thanks for catching this!
