Check version number before uploading to pypi

[ailzhang]

I forgot to upgrade version number in rc-v1.1.1 branch and had to yank this release due to the following two issues:

• some of the built wheels have 1.1.0 in their names which is unexpected, they should use 1.1.1 which is manually specified when I started the workflow.
• can we also add another check to make sure the version printed in ti.init aligns with tagged version before uploading to pypi?
