Add `from_toml` filter (#12081) (#12081)
* Add `from_toml` filter (#12081)
* Use tasks/main.yml instead of runme.sh for integration tests
* Renamed filter back to to_toml.py, moved from_toml filter to its own file making use of python's native tomllib
* Remove task to install tomlkit library as it's no longer required for the from_toml filter
* Replace deprecated t.Mapping with collections.abc.Mapping (https://docs.python.org/3/library/typing.html#typing.Mapping)
* Type is not determined when function is called. Let isinstance check ensure value has string type.
(cherry picked from commit 8faf8c3838)
