🐛 Bug Report: Documentation for many environment variables point to outdated links

[dcowan-london]

👟 Reproduction steps

Many Function templates require environment variables, which are specified in each templates README.md. Many of these have outdated documentation links.

For example, many Function templates require an environment variable APPWRITE_API_KEY. The README.md in each Function template contains a link to https://appwrite.io/docs/getting-started-for-server#apiKey, which no longer exists.

👍 Expected behavior

(Example)
The APPWRITE_API_KEY Documentation link should point to https://appwrite.io/docs/advanced/platform/api-keys

👎 Actual Behavior

(Example)
The APPWRITE_API_KEY Documentation link points to https://appwrite.io/docs/getting-started-for-server#apiKey

🎲 Appwrite version

Different version (specify in environment)

💻 Operating system

Something else

🧱 Your Environment
