Add a mailmap entry for y21

Located this running some scripts to find log duplicates.
r? @y21

Thanks! Could this just use y21 for the name? IIUC, this file is used by git to map a canonical email address to a contributor having multiple names in the history and the name here is what would be shown by commands like shortlog, right? I think having that for the name would be more useful then

[tgross35]

That is correct! Most people put their name rather than their GH profile since it's mostly for the thanks page https://thanks.rust-lang.org/rust/all-time/. But if you still prefer, I'm happy to change it to y21 :)

[y21]

(oops I forgot to actually send what I typed) Ah yeah, I'd still prefer that ^^

[tgross35]

Sure, updated!

Thank you, lgtm! @bors r+ rollup

Ah wait actually -- is this file supposed to be sorted (and so y should go near the end of the file instead)? It looks a lot like it's sorted.

@bors r-
If this is fine feel free to r=me again. Maybe I should have also waited for CI to finish first.

Oops, you're right; we don't actually enforce it though, and there are a handful of unsorted entries (probably wouldn't be a bad idea). Moved you to the end.
