[llvm] Remove 'vectorizers' label from PR labeler (PR #67810)

[Vlad Serebrennikov via llvm-commits]

https://github.com/Endilll created https://github.com/llvm/llvm-project/pull/67810

It's subsumed by an order of magnitude more popular 'vectorization' label that is applied for the same path patterns.

Statistics (issues and PRs together):
`vectorization`: 91 open, 91 closed
'vectorizers': 8 open, 5 closed 

All 'vectorizers' usages has occurred in just the past 2 weeks, and likely by our bot.
