fix(workflow): use correct input variable for release-create step

[wojiushixiaobai]

The release-create step was using an incorrect variable name (github.events.input.tag), which resulted in the just release-create command being called without the required tag argument. This commit updates the workflow to use the correct variable (github.event.inputs.tag), ensuring the tag is properly passed to the command.

Thanks, sorry about that! I had this in 60711c4 which I used for yesterday's release, but I forgot to open a pull request, so I'll merge yours. :)

BTW I will take a look at your question about loongarch support soon - I think I would like to merge support into this repo so you no longer have to maintain a fork (and deal with any bugs in our release process :) ).
