[FIX] web: fix the test case related to the year

Before this commit, since we are no longer in 2023, the test failed
because there is no longer 2021 in the filters dynamically added in the
dropdown of the date filter. The reason is now we have the current year,
the previous one, and the one before, that is, 2024, 2023, 2022.

This commit adds a patchDate to be sure we will start the test in 2023,
to get the expected filters displayed (2023, 2022, 2021).

closes #147899
