Fix doc comments in Process.fs

[Numpsy]

The Exec functions have a parameter called 'dir' but the doc comments have 'directory', so this just makes them consistent

(Just noticed a warning in Rider when looking at #2880 and though they should be consistent)

Pull request overview

This PR updates XML doc comments in Fake.Core.Process’s Shell API to match the actual optional parameter name (dir) and fixes a small grammar issue in the summary text.

Changes:

• Update <param> name from directory to dir for Shell.Exec and Shell.AsyncExec.
• Fix “it’s completion” → “its completion” in the Shell.Exec summary.

Are there any relevant comments from Copilot?

[Numpsy]

I wasn't looking at anything other than the param names before, but looking at the code now the 'async' function doesn't look very async? (actually it looks the same as the implementation of the not-async version)

[xperiandri]

Yep so I think we should get rid of that
