Enable deprecation: execute-macro-release

[emmyoop]

Introduced in: v0.17.2
In the last week, raised by: 0 projects

Pretty straightforward: as the deprecation warning message states, we should remove the release arg from the execute_macro method. I don't think we need to worry too much about moving text_only_columns up one positional argument, but it may not be a bad idea to leave a placeholder in its spot.

Then, we can remove it from the list of active deprecations.
