Steps To Reproduce

Here my server.ps1 file

server.ps1

Start-PodeServer {
    
	New-PodeLoggingMethod -Terminal | Enable-PodeRequestLogging
	New-PodeLoggingMethod -Terminal | Enable-PodeErrorLogging
	Add-PodeEndpoint -Address 127.0.0.1 -Port 8080 -Protocol Http
	#Initialize OpenApi
	Enable-PodeOpenApi -Path '/docs/openapi' -DefinitionTag 'user' -DisableMinimalDefinitions

	# OpenApi Info
	Add-PodeOAInfo -Title 'Swagger Petstore - OpenAPI 3.0' `
		-Version 1.0.17 `
		-Description 'This is a sample Pet Store Server based on the OpenAPI 3.0 specification. ...' `
		-TermsOfService 'http://swagger.io/terms/' `
		-LicenseName 'All rights reserved' `
		-LicenseUrl 'https://localhost' `
		-ContactName 'API Support' `
		-ContactEmail 'example@example.com' `
		-ContactUrl 'http://example.com/support' `
		-DefinitionTag 'user'

	# Endpoint for the API
	Add-PodeOAServerEndpoint -url '/api' -Description 'default endpoint' -DefinitionTag 'user'

	# OpenApi external documentation links
	$extDoc = New-PodeOAExternalDoc -Description 'Find out more about Swagger' -Url 'http://swagger.io'
	$extDoc | Add-PodeOAExternalDoc

	# OpenApi documentation viewer
	Enable-PodeOAViewer -Type Swagger -Path '/docs/swagger'  -Title 'Swagger' -DefinitionTag 'user'
	Enable-PodeOAViewer -Bookmarks -Path '/docs' -Title 'Bookmark' -DefinitionTag 'user'
	
	Select-PodeOADefinition -tag 'user' -ScriptBlock {
		Add-PodeRouteGroup -Path '/api' -Routes {
			Add-PodeRoute -Method Get -Path '/v4.2/:potato' -ScriptBlock {
				Set-PodeResposneStatus -Code 400
				Write-PodeJsonResponse -Value $WebEvent.Parameters['potato']
			} -Passthru | Set-PodeOARouteInfo -Summary 'Failed' -Description 'Failed' -OperationId 'Failed' -Passthru | `
				Set-PodeOARequest -PassThru -Parameters ( 
				New-PodeOAStringProperty -Name 'potato' -Description 'Potato Name' -Required | 
				ConvertTo-PodeOAParameter -In Path -Required 
			)
			Add-PodeRoute -Method Get -Path '/:potato' -ScriptBlock {
				Set-PodeResposneStatus -Code 200
				Write-PodeJsonResponse -Value $WebEvent.Parameters['potato']
			} -Passthru | Set-PodeOARouteInfo -Summary 'Worked' -Description 'Worked' -OperationId 'Worked' -Passthru | `
				Set-PodeOARequest -PassThru -Parameters ( 
				New-PodeOAStringProperty -Name 'potato' -Description 'Potato Name' -Required | 
				ConvertTo-PodeOAParameter -In Path -Required 
			)
		}
	}
}

And it's generating the following openapi definition
See "/v4\\.2/{potato}" -> Should be "/v4.2/{potato}"

Expected Behavior

The . shouldn't be replace in the OA Definition.

Platform

• OS: Windows
• Browser: Chrome/Edge
• Versions:
  • Pode: 2.11.0
  • PowerShell: 5.1 and 7.4.5

Additional Context

I've pretty much know where the issue is coming from. In Private/Helper.ps#L3149 it escape the whole path for Regex control char. I'm not sure if it's required somewhere else or not.
