Jekyll Include Cache Files

Bug fixes

• Name the Jekyll 4 cache JekyllIncludeCache instead of Module, and clear the digest cache on each rebuild so jekyll serve no longer grows without bound (#43)

Performance

• Keep rendered includes in memory instead of writing each one to .jekyll-cache and wiping it before every render. Rebuilds were about 27% faster in a 1,000-page benchmark with identical output (#43)

Dependencies

• Declare required_ruby_version >= 3.0 (#32)

Infrastructure

• Bump github/codeql-action (#33, [#37], [#41], [#42], [#44])
