Update Delegated OAuth to 1.0.2

[rmccue]

Seeing as we control this, we could use a ~ here?

[roborourke]

That does the same as ^ right? I'm good with that, think we stopped as JH had feelings about it but for our own deps I think it'll save us some work in general.

[rmccue]

Yeah, functionally equivalent here. I'll follow up with another PR for it.

[hm-backport]

The backport to v2-branch failed:

Commits ["a5844bf2abcb543566217a46f8dd5d193f44274e"] could not be cherry-picked on top of v2-branch

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub.
git fetch
# Create new working tree.
git worktree add .worktrees/backport v2-branch
# Navigate to the new directory.
cd .worktrees/backport
# Cherry-pick all the commits of this pull request and resolve the likely conflicts.
git cherry-pick a5844bf2abcb543566217a46f8dd5d193f44274e
# Create a new branch with these backported commits.
git checkout -b backport-25-to-v2-branch
# Push it to GitHub.
git push --set-upstream origin backport-25-to-v2-branch
# Go back to the original working tree.
cd ../..
# Delete the working tree.
git worktree remove .worktrees/backport

Then, create a pull request where the base branch is v2-branch and the compare/head branch is backport-25-to-v2-branch.
