Remove requirement on pyramid 2.x

It appears that we don't actually need pyramid 2.x except for the
"official" support designation.

* 3.10 support was added in a no-op PR:
  https://www.github.com/Pylons/pyramid/pull/3689

* 3.11 support was added in a PR which removed the ldgettext and
  ldngettext functions:
  https://www.github.com/Pylons/pyramid/pull/3717
  (We don't use these functions in any of our codebases.)

* 3.12 support is being added in a no-op PR:
  https://www.github.com/Pylons/pyramid/pull/3737

As such, I believe we can get away with still using pyramid 1.x with
3.10/3.11/3.12.
