Fix 'Allow select actions' wording and description

[lucascosti]

Replaces PR: #941, and done in collaboration with @Simran-B

Why:

• The description for Allow select actions does not mention that local actions are also allowed when using that setting.
• The docs incorrectly name the setting Allow specific actions, when the label in the UI is Allow select actions.

What's being changed:

Adds some wording to the description stating that local actions are also allowed, and fixes the label text.

Thanks for the original content for this, @Simran-B! Because I'm the creator of this PR, we have to wait until someone else on the docs team reviews and approves it 🙂

joshmgross said that

Local actions also includes any within an enterprise account.

It still doesn't say so here:

When you enable local actions only, workflows can only run actions located in your repository or organization.

Should we improve the description of "local actions" in this PR too?
