Update the Remotion skills CLI commands

[JonnyBurger]

Make the existing Remotion skills commands non-interactive and give update the explicit list of Remotion skills.

npx remotion skills add should invoke:

npx --loglevel=error skills@1.5.20 add remotion-dev/skills --yes

npx remotion skills update should invoke:

npx --loglevel=error skills update remotion-best-practices remotion-captions remotion-create remotion-docs remotion-interactivity remotion-maps remotion-markup remotion-multimedia remotion-render remotion-saas remotion-upgrade --yes
