Added lolbas iediagcmd.exe as discovered by Adam @hexacorn (#199)

Everything looks good, confirmed working on Windows 10 & 11, merging changes:

* Added 'Execute' lolbas for iediagcmd.exe

* Added missing fields from the template

* Update Iediagcmd.yml

Made corrections

* Update Iediagcmd.yml

Removing trailing spaces

* Update Iediagcmd.yml

removing empty fields

* Minor changes

* Update Iediagcmd.yml

Removing space before first "&". When setting the Environment variable, it's picking up the space so the path seemed to be "c:\test \", which is why tests are failing.

* Adding Windows 11 support
