Subject: [PATCH 2/9] Add automatic VERSION setting for nightly builds

- Modified build.yml to accept optional version input parameter
- Modified nightly.yml to calculate VERSION from build date in format yymmddb
- VERSION is passed as PLATFORMIO_BUILD_FLAGS to override default in wled.h
- Other workflows (wled-ci.yml, release.yml) unchanged and will use default VERSION

Subject: [PATCH 3/9] Implement nightly VERSION automation using PlatformIO
 script

- Created pio-scripts/set_nightly_version.py following existing set_version.py pattern
- Script sets VERSION to yymmddb format with build number 0 for nightly builds
- Modified build.yml to accept nightly_build boolean input
- Modified nightly.yml to pass nightly_build=true flag
- Added set_nightly_version.py to platformio.ini extra_scripts
- Uses WLED_NIGHTLY_BUILD environment variable to conditionally set VERSION

Subject: [PATCH 7/9] Fix changelog generator parameter name from
 exclude-labels to excludeLabels

The action janheinrichmerker/action-github-changelog-generator@v2.3 expects
camelCase parameter names. Changed 'exclude-labels' to 'excludeLabels' in both
nightly.yml and release.yml to fix the nightly release action failure.

The v2.4 release fixes the deprecated set-output command by using GITHUB_OUTPUT
environment file instead. This eliminates the deprecation warning in nightly builds.
