Revert fspath deprecation

It is not clear yet how we should proceed with this deprecation
because `pytest.Item.reportinfo` is public API and returns a `py.path` object,
and is not clear how plugins and our examples should handle that.

Reverting just the deprecation aspect of #8251 so we can get a 7.0.0 release out.

We will reintroduce the deprecation later once we have a clear path moving forward with replacing `reportinfo`.

Closes #8445
Closes #8821
