Dialects section bug for alignment of "PDLExtensionOps" on mlir page.

Attaching image of the issue I stumbled upon luckily when my mouse pointer was idle, There seems to be a hidden link for "PDLExtensionOps" before the "acc" Dialect. When right clicked it opens this page - > https://mlir.llvm.org/docs/Dialects/PDLExtensionOps/

I tried to verify with firefox and chrome, same issue.

If you want to debug this, run ninja mlir-doc and look into why tools/mlir/docs/Dialects/PDLExtensionOps.md does not generate the same header as the other dialects in the same directory (It's table-gen generated)
