ci: harden PSScriptAnalyzer step against internal analyzer NREs

PSScriptAnalyzer 1.25.0 has been throwing intermittent NREs and parameter
binding errors during recursive analysis on Linux runners when invoked with
-RecurseCustomRulePath but no -CustomRulePath. The switch is a no-op without
a custom rule path anyway, so it's removed. The call is wrapped in try/catch
that falls back to per-file analysis if the recursive call throws, so a
transient analyzer fault no longer fails the workflow.
