fix: run framework update non-interactively in CI

[Aaravanand00]

The framework update command was running interactively and waiting for confirmation in CI.

This change runs it non-interactively by piping y into the command so the workflow can complete successfully.

Hi @nishantwrp,

I’ve updated the workflow as suggested.

• Replaced the interactive command with yo joplin --update --silent.

• Moved the “Check for changes” step to run right after the framework update
  step, before npm install

This should address both issues. Please take a look is this ok?

Hi @Aaravanand00, the workflow still doesn't run correctly. https://github.com/joplin/plugin-templates/actions/runs/22628514766/job/65571690685

Can you please fix? Also, please test your changes locally as well before raising a pr.
