fix: missing email button padding

[Funk66]

Description

The py-* and px-* classes don't work in the Button element - email buttons are rendered without padding.

The text is still slightly misaligned vertically owing to the spacing reserved for letter descendants, which are not present in uppercase text.

This commit also fixes a small syntactic error in the punctuation of the email message.

How Has This Been Tested?

With npm run email:dev.
