Fix build errors, add hardcoded ACP explainer

[meaghanfitzgerald]

Why this should be merged

the build has been broken due to invalid sourceBaseUrls in remoteContent.js. These Urls point to .md files in remote repositories (ie. https://github.com/ava-labs/avalanchego/) that are pulled into docs via docusaurus-plugin-remote-content community plugin.

I wrote a detailed guide on how I implemented docusaurus-plugin-remote-content to pull remote docs. Many FAQs are answered there.

How this works

• changes the invalid URLs to valid URLs
• removed the ACP remote URLs and replaced with a hardcoded file in docs/learn/acp.md

How these changes were tested

yarn build yarn start
