Subject: configure: correct the wording when checking grep -E
X-Git-Tag: curl-7_86_0~262

configure: correct the wording when checking grep -E

The check first checks that grep -E works, and only as a fallback tries
to find and use egrep. egrep is deprecated.

This change only corrects the output wording, not the checks themselves.

Closes #9471
