Use base64 to encode binary string to text and decode it back to binary. This is pretty standard trick.

First, encode at home:

echo "$MY_BINARY_SECRET" | base64 --wrap=0 > secret.b64

--wrap=0 to make the output text one long line; useful for echo below.

Upload text file secret.b64 as the secret to GitHub. Decode it using

echo -n "${{ secrets.MY_BINARY_SECRET }}" | base64 --decode > binary.file

Advice: first try decoding locally and compare with the original string. Must be the same.
