pac power-fx should accept optional parameter for formula separators

[Zerajima]

Power-fx syntax changes depending on how decimal separator is configured on the machine: https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/global-apps#formula-separators-and-chaining-operator. Specifically, the list separator and the chaining operator and different. This can cause issues when you want to share your script with someone else, if he uses a different decimal separator.

Could an optional parameter be added to all pac power-fx commands, that allows us to specify, which separator should be used when evaluating the script?
