Drop now-invalid allow-reresolve input from downgrade workflow(s)

[ChrisRackauckas-Claude]

What

Remove the now-invalid allow-reresolve: input from the downgrade workflow(s).

The centralized SciML/.github downgrade workflows (downgrade.yml and
sublibrary-downgrade.yml) are being changed to always use
allow_reresolve: false and to drop the allow-reresolve workflow_call
input entirely (see SciML/.github#71). Once that merges and @v1 is retagged,
any caller still passing allow-reresolve: would fail with an invalid-input
error. This PR removes that line so this repo keeps working.---
