name: Update Version

# This workflow updates version information in 'ALVersionInfo.py' with build metadata.
# In progress, it will generate two version files, the first one is locate in 'src/gui/ALVersionInfo.py',
# and the second one is locate in 'src/gui/temp/ALVersionInfo.py'. The first one is use
# in the release process, it only update the version and tag name. The commit and build infomation
# is 'local' or 'null'. All of them will finally archive as artifacts.
#
# It is triggered when called by the release workflow.
