Summary

This PR prepares the 22.0.0 release by promoting all [Unreleased] changes in RELEASE_NOTES.md to a versioned release entry.

Changes Included

Added

• FsDocsAllowExecutableProject MSBuild property — include Exe/WinExe projects in API docs (#918)
• {{fsdocs-logo-alt}} substitution via (FsDocsLogoAlt) property, defaulting to "Logo" (#626)

Fixed

• Improved error message for undefined named code snippets (#982)
• HTML-encode XML doc text nodes / (see cref) values to prevent HTML injection (#748)
• Add uppercase output kind (e.g. HTML, IPYNB) to ConditionalDefines (#693)
• Strip #if / #endif marker lines from LiterateCode source before highlighting (#693)

Changed

• Update FCS to 43.10.100 (#966)

Version Rationale

The FCS version bump (43.9 → 43.10) together with the new HTML encoding behaviour (output format change) and the new MSBuild properties warrant a major version bump per this project's conventions.
