Minor cleanup

[jsoref]

• Split from Remove node_modules and compile typescript into minified scripts #2578

• spelling: in case -- grammatical fix
• spelling: macos -- branding fix
• Strip trailing whitespace generated by ruamel-yaml -- quality of life change -- editors do not like trailing whitespace and have a tendency to strip them (which is problematic given that there's a second related file) -- ruamel-yaml is currently pinned to an out-of-date version, but at some point, I'd be inclined to file a bug against it if I could reproduce this behavior in the current version
• Give expected-queries-runs permissions
• Fix publish-immutable-action version -- This is odd, I filed Advice in readme appears contradictory but is at least out of date actions/publish-immutable-action#212 about it
• Conditionally clear runner cache -- This relates to making nektos/act happy (there's a second bigger bug that means that act doesn't work at all, I've poked it)
