FIxed the issue with decode #786

i hate macos 16 for this

i just corrected a little mistake @hikarunoryoma made with
Buffer.from he did buffer.from(base64).toString("base64") which essentially takes in the base64 as a utf-8 and tries to convert it into a string of type "base64"

but instead it should be
buffer.from(base64, "base64).toString() which is telling the buffer object to take that base64 and tell it it's a type of base64, and then stringify that buffer

These changes in .gitignore are OK, but can you create a separate PR for them? I prefer to have self-contained PRs.

[haouarihk]

i see sorry

[marco-c]

No problem, thank you for working on the PR!

BTW, you don't need to close and create a new one, you can also just update an existing PR.
