feat: separate CLI Tutor Mode helptext

[jessicaschilling]

Closes #1686.

This PR separates out the i18n key cliModal.extraNotes so we can display different CLI Tutor Mode modal helptext in different situations:

• "IPFS Config" modal (already existed)
• "Set Pinning" command in Files screen context menu (new in this PR)

To do:
The i18n keys are split out, but I'm missing something that's probably obvious in terms of getting helptext to display when a tutor-mode modal is invoked from the context menu. @lidel or @rafaelramalho19, do you mind a quick look if you get the chance? 🙏

Thanks, @rafaelramalho19, but can you please look at the "to do" item when you get a chance? Thank you!

@jessicaschilling by help text you mean the title html attribute?

[jessicaschilling]

@rafaelramalho19 - cliModal.ExtraNotes is customized as part of this work (that's the helptext), but I can't get it to display conditionally for the "Set pinning" command under the "three dots" context menu.

Thanks, @rafaelramalho19!

@lidel - can you please have a look when you get the chance? Would be one more item done in the pinning epic ...

LGTM but we should make key names more explicit,
will save us time when debugging bugs in the future :)

@jessicaschilling mind updating places where below keys are used?

@lidel - good call. Updated. Please merge at your leisure ...
