fix: [M3-8067] - Remove duplicate speedtest helper text in Create Cluster form

[mjac0bs]

Description 📝

We ended up with two speedtext helper texts displaying on the LKE Create Cluster form. I'm not entirely sure why this happened, but I think it was a combination of deciding where to place the helper text in this form once the pricing link was added and changes to RegionSelect and/or Autocomplete that made the helper text show up where it should be, when it wasn't originally due to some bug.

Changes 🔄

• Removed one of the helper texts.

Confirmed removal of duplicate speedtest helper text 🧹 . My theory is that it was overlooked as part of resolving a merge conflict 🤔
