Update docs for delta account specification

[janbridley]

Description

Accounts on delta are automatically suffixed with -cpu or -gpu. The documentation has been updated to reflect this by indicating only the account prefix must be supplied.

I'm not sure if this is the best way to document this, but Maria and I encountered (minor) confusion due to this behavior.

This is mentioned in the howto guide:

row/doc/src/guide/howto/account.md

Lines 23 to 25 in 4cf759b

	> Note: NCSA Delta assigns `<prefix>-cpu` and `<prefix>-gpu` accounts. Set
	> `submit_options.delta.account = "<prefix>"`. **Row** will automatically append the
	> `-cpu` or `-gpu` when submitting to the CPU or GPU partitions respectively.

I agree it should also be mentioned in the Delta cluster section.

I updated the book to pull those specific lines from the hoot section. I think the consistency in wording is nice and it results in no text duplication (although the link could break if we update the howto page) addressed using anchors

Thanks!

The anchored include is a good solution to keep duplicate information in sync.
