[Enhancement] Add an option to automatic deleto or replate commas within matomo tag templates

[SW-Vincent]

Considering CSV exports are comma separated, comas that could appear within events or page titles would interfere with data exports for this format.
As some variables are dynamic, it is not excluded that this issue may happen from times to times (espescially for clicktext variable).

Therefore, an option to automatically delete or replace commas within Matomo tag templates would be useful.

@SW-Vincent You can use a "Custom JS function" variable and replace the unwanted values.
