ci: revert ee rebase changes to dependabot.yaml

[NicholasBlaskey]

Ticket

Description

This commit I think was a mistake from the ee repo merge.

This is undoing that change with

git checkout 283daab2d8eed70dae568ac7ac80db60e25be9e0~1 -- dependabot.yml

Test Plan

see if we get dependabot prs after this
