Update dremio-setup.md

[AndyHunt66]

The sentence
"See Support Keys in the Dremio documentation for the steps." makes no sense in this context. There is nothing on this page that requires the setting of a support key, apart from if you're using a PAT and haven't yet set up your Dremio system to use PATs, and even then, the wrong page is linked to.

hey @AndyHunt66 , thanks for opening this up and great catch! based on this pr https://github.com/dbt-labs/docs.getdbt.com/pull/6689/files, it looks like line 40 was missed since support keys aren't required anymore. thanks for catching and opening this up! ✨
