[jkandasa]

Changes

bump PAC dependency to 0.19.0 (from v0.17.2)
bump pipelines dependency to 0.47.0 (from 0.45.0) and addresses breaking changes

• There is a breaking change in pipelines 0.47 release [TEP-0091] change feature flag resource-verification-mode to trusted-resources-verification-no-match-policy pipeline#6324
• Introduced new field trusted-resources-verification-no-match-policy and removes resource-verification-mode under tekton pipelines

Removed verification-mode

Actually we have to deprecate resource-verification-mode in favor of trusted-resources-verification-no-match-policy, But I removed it completely. why?

• Adds resource-verification-mode and enable-provenance-in-status fields for Pipelines #1194
  • introduces resource-verification-mode
  • there is a mistake in the field name, it should be resource-verification-mode, but implemented as verification-mode refer
  • So verification-mode field never used in pipelines, hence I removed the field completely.
