docs: v0.7.5 install pins (#2256)

The install pins on main move from `v0.7.4` to `v0.7.5`, now that 0.7.5 is published: the README's `skills add` lines, its install-script lines and the sentence naming the release, plus the same install-script lines in `docs/reference/getting-started.md` and the example tag in `docs/reference/quickstart.md`. `docs/reference/whats-new.md` stays at main's note, because it names `packages/cli`'s version. Text only.

 If a provider isn't signed in yet, the last step reports `FAILED [4/4]`, and `rig setup` lists the sign-in under "Some steps need attention". If the only remaining failures are provider sign-ins, the install steps finished; sign in to each selected provider as below and continue.
