windows: Fix path parsing issue when launching Zed from command line (#15856)

Closes #15826
Closes #16068

When launching zed from the command line, the path parsing prefixes with
`\\?\`. Some LSP servers do not support this type of path, so here I
just simply remove the prefix.

Release Notes:

- N/A
