ci: fix release workflow condition (#132)

This job should not have run:
https://github.com/oxc-project/eslint-plugin-oxlint/actions/runs/10327248826/job/28592123359

I accidentally put quotes around the
[contains](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/expressions#contains)
function in #131 - however, removing them generates a YAML error with
the colon in `'release: v'` (`"release: v"` also fails). A workaround is
to use the
[startsWith](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/expressions#startswith)
function.
