Umbraco CMS - Improve Release Notes

Takes a file of auto-generated GitHub release notes and produces an improved version that:

1. Is complete — every merged PR carrying the release/<version> label appears.
2. Is well-categorized — every PR sits under the most appropriate heading.
3. Is free of noise — purely-internal entries of no value to a reader are removed.

The result is written to a new file alongside the input, so the user can diff the two.

Run autonomously. Do NOT use AskUserQuestion once the required arguments (version and input file path) are available — only ask if one of them is missing from $ARGUMENTS and cannot be inferred (see Arguments). Beyond that, make the categorization calls yourself using the rules below; if a handful are genuinely borderline, place them anyway and note the borderline ones in your closing summary so the user can override.

Arguments

$ARGUMENTS contains two values:

1. Version — e.g. 17.5.0, 18.1.0. The GitHub label to search is release/<version> (so version 17.5.0 → label release/17.5.0).
2. Input file path — full path to the text file holding the auto-generated notes (e.g. C:\Temp\release-17.5.0-rc.md).
