[PATCH 3/3] gitmailmap.txt: fix rendering of e-mail addresses

Both AsciiDoc and Asciidoctor are eager to pick up the e-mail addresses in this document and turn them into references at the bottom of the manpage / clickable links. We don't really need that for these dummy addresses. Spell "@" as "@" to make them not do this. In the open block, we can instead avoid this by indenting the contents, similar to the earlier blocks.

Fix a backtick which should have been a single quote mark. With all the quoting that is going on around here, this mistake trips up the parsing and rendering quite a bit.

Before this commit, we have the same failure mode with AsciiDoc 8.6.10 and Asciidoctor 1.5.5, and this change makes both of them happy.
