fix: point console links at final URLs, correct Runpod brand casing

[danstotts-ops]

Two small README fixes, in separate commits so either can be dropped.

1. Console links point at legacy paths

Three links use www.runpod.io/console/*, which 301s to the console subdomain. Readers take an extra hop, and link graphs record the citation as indirect rather than direct. Surfaced while triaging an Ahrefs lost-backlink report, where these showed up as lostredirect.

Verified each destination returns 200 before changing it:

Was	Now
www.runpod.io/console/serverless/user/settings	console.runpod.io/serverless/user/settings
www.runpod.io/console/serverless/user/endpoints	console.runpod.io/serverless
www.runpod.io/console/hub/runpod-workers/worker-comfyui	console.runpod.io/hub/runpod-workers/worker-comfyui

Worth flagging the middle one: the endpoints path resolves to /serverless, not to a like-named path on the console subdomain. A mechanical prefix swap would have produced console.runpod.io/serverless/user/endpoints, which is a 404. Nothing currently links there, but it is an easy trap if anyone repeats this by hand elsewhere.

No user-facing breakage today, every existing link works. This is hop removal and citation hygiene.

2. Brand casing (separate commit)

The brand is Runpod, not RunPod. The README had 11 of the old casing and none of the current one. Same correction already merged in the docs repo.

Prose only. Every URL in the file already uses lowercase runpod, and the script aborts if the string appears inside a link, so no paths or identifiers moved.

Note on Docker Hub

release.yml, manual-push-dockerhub.yml, and manual-build-all.yml all sync this README to the Docker Hub description, so merging propagates there on the next release without any separate step.

@rutvik-runpod @celine-runpod could one of you take a look when you get a chance?

Two independent commits, happy for you to take just the first if the brand casing one is noise for this repo.

Main thing worth a second pair of eyes: the endpoints link resolves to /serverless, not to a like-named path on the console subdomain. console.runpod.io/serverless/user/endpoints is a 404, so this isn't a mechanical prefix swap. Same trap likely exists in other repos that reference legacy /console/* paths.
