Fix the release guard that would have failed every build

The step that checks a built release actually contains the CurseForge key used
Select-String -Encoding Byte to grep the DLL. There is no byte mode: -Encoding
takes a character encoding and rejects "Byte" by validation, so the step would
have failed on a parameter error before checking anything -- and taken every
release with it, whether or not the key was there.

Reads the file as bytes and searches the raw text instead. Verified both ways:
it finds the attribute in a build that has one, and does not in a build that
does not.
