🪲 [Fix]: Rename and allow pipeline input on function to get installation token (#139)

## Description

- Renamed `Get-GitHubAppInstallationAccessToken` to
`New-GitHubAppInstallationAccessToken`, aligning with that this is a
post method, and not just a get.
- Allowing the function to also take `Get-GitHubAppInstallation` results
as pipeline input.
