fix(lrt): scope skip-list update to install/upgrade only

[Copilot]

LRT on Azure was failing due to skip-delete-resources-list.txt being unconditionally overwritten every run regardless of whether install/upgrade occurred.

Changes

.github/scripts/manage-radius-installation.sh

• Extract kubectl UCP resource snapshot into save_skip_resources_list() helper (with error handling); call it only in the install and upgrade branches — not the version-match no-op path

.github/workflows/long-running-azure.yaml

• Remove the unconditional "Create a list of resources not to be deleted" step; the snapshot now lives inside manage-radius-installation.sh and is scoped to install/upgrade only

Pull request overview

Fixes Azure long-running test (LRT) failures by ensuring skip-delete-resources-list.txt is only refreshed when Radius is actually installed/upgraded, instead of being overwritten on every run.

Changes:

• Move UCP resource snapshot generation into save_skip_resources_list() inside manage-radius-installation.sh.
• Call the snapshot helper only on install/upgrade paths (not on the version-match no-op path).
• Remove the unconditional workflow step that regenerated the skip list every run.

File	Description
.github/workflows/long-running-azure.yaml	Removes the always-run kubectl snapshot step; relies on the script to generate the skip list only when needed.
.github/scripts/manage-radius-installation.sh	Adds save_skip_resources_list() helper and invokes it from install/upgrade branches.

.github/workflows/long-running-azure.yaml:282

• After removing the step that always generated skip-delete-resources-list.txt, this cache save step can run when the file was neither restored (cache miss) nor created (version-match no-op). actions/cache/save typically fails when the specified path doesn't exist, which would break the workflow even though skipping install/upgrade is a valid outcome. Guard this step with an if that checks the file exists (or create a minimal file in the no-op path without overwriting an existing one).
