fix: remove dependency on deprecated nanolayer package

[kdowney-lot49]

Description

Replaced deprecated nanolayer package with just a plain shell script using curl following the recommended installation method at https://buf.build.

NOTE: due to a pre-commit hook issue I did not remove library_scripts.sh as part of this PR, though it is no longer needed. It seems like the toodaloo hook doesn't handle removed files properly.

How to test

Ran locally in devcontainer with no issues on Linux ARM.

Evidence:

vscode /workspaces/devcontainers (main) $ file /usr/local/bin/buf
/usr/local/bin/buf: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), statically linked, BuildID[sha1]=df7f31ef6d82c378dfcb103a6e6f0a7887387263, stripped
vscode /workspaces/devcontainers (main) $ uname -a

Previously the installer downloaded the Linux RISC-V binary.

@mrsimonemms I also ran pre-commit autoupdate to upgrade your built-in pre-commit hooks, but feel free to exclude that from merge if you want the fix to be more limited.

Can you rebase the commit with the signed off by line please?

[kdowney-lot49]

@mrsimonemms it looks like merge might block due to lack of signature on the original commit. If that's the case I will have to take care of that in the evening because it's a more involved fix than the signoff-off rebase.
