Add .pst1 file extentsion to better support Pester Tests
Currently there is no way of telling whether a PowerShell Script (.ps1) is full of pester (or perhaps Gherkin) tests or if it is an actual script without adding .tests. in between the file name and the ps1 extension
This would make it cleaner in visibility as currently you could have the following
Install-MyModule.ps1
MyModule.psd1
MyModule.psm1
MyModule.psm1-help.xml
And then the tests files could be the following
MyModule.Tests.ps1
Import-MyModule.Tests.ps1
To combat this I would propose that tests could be formed in a file with a pst1 extension
