docs(run-a-base-node): stale base-org/node repository links should point to base/node

[Sertug17]

Bug

The run-a-base-node.mdx page contains two stale links pointing to the old base-org/node repository:

1. In the intro: https://github.com/base-org/node
2. In "Running a Node" step 1: https://github.com/base-org/node

The repository has been moved to https://github.com/base/node.

Steps to Reproduce

1. Go to https://docs.base.org/base-chain/node-operators/run-a-base-node
2. Click any of the "node" links
3. They point to github.com/base-org/node instead of github.com/base/node

Proposed Fix

Replace all occurrences of https://github.com/base-org/node with https://github.com/base/node in docs/base-chain/node-operators/run-a-base-node.mdx.

I'd be happy to open a PR for this fix.

Hi! I opened PR #1297 to fix this. Updated both run-a-base-node.mdx and troubleshooting.mdx to point to the correct base/node repository.
