Add a button to jump to first and latest commit

Hey! I’m the one who opened the issue to add the repo-age feature, because I think it’s really interesting to know how a project was… in the beginning, and what was done first. Sometimes I spend a lot of time spamming the “Older” button to see what the first commits were. So if we could add these buttons it would be really really useful: (or first page/last page, some websites use this term)

It would be very easy to make them, as we could just get the first commit hash, the number of commits and then generate an URL like https://github.com/Androz2091/AtlantaBot/commits/master?after=FIRSTCOMMITHASH+NUMBEROFCOMMITS&branch=master.

I am not sure how the layout should be. But if anyone wants to send a PR, cherry-pick https://github.com/sindresorhus/refined-github/commit/e4728b616da839c8d0761700efbc74510aad29d3 to extract the function https://github.com/sindresorhus/refined-github/issues/3455#issuecomment-673753201

If we extract this part of the function, this feature would come for free since the commitCount would already be cached:

https://github.com/sindresorhus/refined-github/blob/6bba1c5de1e8b609e010f252d72ff9c63af431a6/source/features/repo-age.tsx#L46-L63

Probably:

export const getLatestCommitInfo = cache.function(async () => {
	const {repository} = await api.v4(`
		repository(${getRepoGQL()}) {
			defaultBranchRef {
				target {
					... on Commit {
						hash: oid
						date: committedDate
						path: resourcePath
						commitCount: history {
							totalCount
						}
					}
				}
			}
		}
	`);

	const {target} = repository.defaultBranchRef;
	target.commitCount = target.commitCount.totalCount;
	return target;
}, {
	cacheKey: () => 'latest-commit-info:' + getRepoURL()
});
