Go to project at /Code/themes/business-time
Update the version in package.json
run vsce publish

To update the Azure hosted git repo you’ll probably need a new Personal Access Token (PAT). Generate that in the UI, then you can use it as the password when using to that remote.
Generate it for “All available organisations”, not just mine.
vsce login mike-healy
git push https://mike--healy@dev.azure.com/mike--healy/Themes/_git/Themes
But maybe the vsce publish command above is enough, and you don’t need to update the repo?
