Add `Update-Version` to `ReleaseTools` module

[andyleejordan]

Pulled out of #3195, I'd really like to add this to the module, but haven't done so yet.

• Update VersionPrefix and VersionSuffix fields in
  PowerShellEditorServices.Common.props
• Update PowerShellEditorServices.psd1 Fix version in PowerShellEditorServices.psd1 PowerShellEditorServices#1455
• Update version, preview, name, displayName, and description fields in package.json
• Delete tools/postReleaseScripts/updateExtensionVersions.ps1
• Commit with Update version for '$version'
• Create Git tag at that commit
• Rename built assets with version instead of -insiders
• Improve grouping of emoji in changelog Whatever
• Exclude "Update CHANGELOG" and "Bump version" PRs from changelog generation
• Fix pipeline to not use BUILD_ID and associated scripts
• Get all PRs not just closed to pending PRs can be included in changelog
