Chore: Pin dateparser version

[erindru]

dateparser==1.2.2 seems to cause some date-related tests to fail

This pins it to <= 1.2.1 which fixes things on a fresh venv. Note that ~= 1.2.1 still causes 1.2.2 to get resolved which causes the tests to fail on a fresh venv

what's the issue?

1.2.2 is an important release because it contains performance fixes i made

Still working on pinning down exactly what causes it, I just wanted to provide an option to move forward in the short term.

Basically, this function started returning None in some situations again.

It appears to be nuanced, im trying to track down the root cause which may be in a transitive dependency.

• Fresh venv, dateparser==1.2.2 resolved - tests fail
• Fresh venv, dateparser==1.2.1 resolved - tests pass
• My existing development venv, manually pip install --upgrade dateparser==1.2.2 - tests pass for some reason

Merging this to unblock the pipeline in the short term, i'll raise another PR when I figure out what the root cause is
