[BUG] Remove unnecessary test_integration skip for PatchTST_v2

[imjimit07]

Description

Fixes #2455

PatchTST_v2 was excluded from test_integration via the tests:skip_by_name tag in _patch_tst_pkg_v2.py. This PR removes the skip so the test runs again.

Investigation

I set up the environment and ran the full v2 test suite for PatchTST_v2. The model passes all tests — there is no underlying bug; the skip (added in the original model commit dd46c99) was simply unnecessary:

pytorch_forecasting/tests/test_all_v2/test_all_estimators_v2.py::TestAllPtForecastersV2::test_doctest_examples[PatchTST_v2] PASSED
pytorch_forecasting/tests/test_all_v2/test_all_estimators_v2.py::TestAllPtForecastersV2::test_integration[PatchTST_v2-0] PASSED

pytorch_forecasting/tests/test_all_v2/test_all_estimators_v2.py::TestAllPtForecastersV2::test_pkg_linkage[PatchTST_v2-PatchTST_v2] PASSED

The tag is removed entirely (rather than set to an empty list), matching the convention of all other v2 packages, none of which carry tests:skip_by_name.

Changes

• Removed "tests:skip_by_name": ["test_integration"] from PatchTST_pkg_v2._tags
