Parsoid: set s-maxage to 60 seconds

[brightbyte]

This sets s-maxage for Parsoid to 60 seconds. If we can get away with this, we can disable active purging (and don't need to implement active purging for the equivalent core endpoints).

Ideally this should have been a config entry managed from scap deployment repo but since we are almost ready to deprecate i think its fine to have it hardcoded.

Some tests fail because of the change of the cache header.

Tests for some old versions of node fail because restbase uses the ?? operator which isn't available until node 14 or so.

Can we stop running tests for node versions oder than 14, and start running tests for node 18 and 20?

The remaining error is:

  1) Language variants
       should request mobile-sections with no variant and store it:

      AssertionError [ERR_ASSERTION]: Expected: sr; Result: undefined
      + expected - actual

      -false
      +true

This test passes for me. Also, it uses an unrelated endpoint (mobile-html).

Not sure how to procede... @johngian do you have an idea what might be going on here?

@brightbyte CI should be passing now. I pinned a dependency to an old version only for dev purposes just for the tests to pass. Also MCS is not supposed to be used. I think its safe to disable the related failures.
