capitalize first sentence of crate delete mail

Tiny thing, kind of bugged me when I received the mail.

I'm not a native english speaker, but since the email begins with "Hi {username}," wouldn't this still be part of the same sentence and thus not have captialization? 😅

It's a very wide convention to capitalize the first sentence after the greeting, although not completely unanimous it's the majority.
See: https://english.stackexchange.com/questions/11906/should-i-capitalize-the-starting-sentence-after-a-greeting-that-ends-in-a-comma

However, as far as I can tell, there is no good reason to oppose conventional style in this case. I would therefore recommend that you stick with the tried-and-true style of using a capital letter to start the letter proper:

Seems reasonable, thanks!

I've rebased this PR and fixed the broken snapshot files in the test suite.

[Uriopass]

Thanks! I should have fixed the snapshot myself. Will do if there's a next time :)

Feel free to take a look at the other email templates. I have a feeling that this might not be the only one that used this pattern 😅
