docs: drop installer flags install.sh/install.ps1 no longer accept

install.sh rejects --no-skills with "unknown option" (rc=1) and neither
installer has --skip-computer-use / -SkipComputerUse: the installer no
longer pre-installs cua-driver at all. Point the skills page at the setup
prompt / hermes skills opt-out, and describe cua-driver as the PM-pinned
package that hermes computer-use install prepares (it never runs the
upstream installer now).

 `hermes skills opt-out` only stops *future* seeding — it never deletes anything already on disk. The optional `--remove` flag deletes bundled skills **only** when they are unmodified (byte-identical to the version Hermes installed). Skills you have edited, skills installed from the hub, and skills you wrote yourself are always kept.
