Translation error in Brazilian translation for pattern-matching.html

[gendx]

See:

• English page: https://google.github.io/comprehensive-rust/pattern-matching.html
• Brazilian page: https://google.github.io/comprehensive-rust/pt-BR/pattern-matching.html.

It looks like the pattern for the character a got translated into two letters um in the code, which breaks compilation.

Maybe the GitHub Actions checking the translations should also run mdbook test on the translated contents to check that the code snippets still compile?

Yes, we actually do exactly that — but it doesn't work as intended until rust-lang/mdBook#1986 is merged.

This was fixed by #416 and will be long-term fixed by rust-lang/mdBook#1986.
