Describe the problem

The readme states

To get the latest stable version of protoc just add this step:

- name: Install Protoc
  uses: arduino/setup-protoc@v3

But this installs version 23.4, while the latest version is 26.0.

When I look at the default version value in action.yml, I see it is set to 23.x. Is it possible to update this version, and maybe even somehow always get the latest value without having to hardcode it?

To reproduce

use arduino/setup-protoc@v3 this gives protoc with version 23.x

Expected behavior

Version 26.0 of protoc

'arduino/setup-protoc' version

3

@pdebakker-auguria Absolutely! Right now, I cannot guarantee that we have enough bandwidth to work on this in the upcoming days. :pray: If you or someone else would like to contribute to this would be awesome! :star_struck:

Regardless of who will implement this, I'll give here some implementation notes:

• Change the default value to latest https://github.com/arduino/setup-protoc/blob/master/action.yml#L7
• If the version variable is latest implement the logic to retrieve and use the latest version. We should change it here https://github.com/arduino/setup-protoc/blob/master/src/installer.ts#L210-L239
• Add a dedicated test

Hi! It's sad to see this GitHub Action is not well maintained anymore. arduino/setup-protoc@v3 still installs protoc v23.4, while the README claims that it installs the latest stable release (which would be v32 now).

I also see that the last time a PR was merged or commented on was in 2024. So before I start preparing a PR with the required changes and a test: Would any of the maintainers still be up for reviewing and merging such a PR?
