support build for v8.4

[ti-chi-bot]

I have already done a preliminary review for you, and I hope to help you do a better job.

This pull request adds support for building version 8.4 and changes the release tags to reflect this new version. However, there are a few potential issues to note:

• The description is very brief and doesn't provide much context about the changes.
• There are no tests included in this pull request, so it's unclear if the changes will work as expected.
• It's not clear if the changes have been tested locally or in a staging environment before being pushed to the main branch.

To improve this pull request, I suggest the following:

• Add more detail to the pull request description to explain why these changes are being made and what impact they will have.
• Add tests for the new version to ensure that everything is working as expected.
• Test the changes locally and in a staging environment before merging to the main branch. This will help catch any issues before they are pushed to production.

Overall, this pull request seems like a small and straightforward change, as long as it's thoroughly tested and the changes work as expected.
