Revert "chore(deps): bump org.jenkins-ci.plugins:copyartifact from 761.vea_2b_25523e84 to 763.v66351b_9c297f in /bom-weekly (#4409)"

Declarative Pipeline tests fail due to copyartifact plugin not loading
on the 2.492.x line.  Fails with the commandL:

  LINE=2.492.x PLUGINS=pipeline-model-definition TEST=InjectedTest bash local-test.sh

This reverts commit fa9855f.
