Convert wiki to documentation

The wiki for this project only has four pages:

• Home - no content
• Concurrency Benchmark Results - very out-of-date, should be deleted
• Schema Collections Supported by GetSchema - could be moved to /docs/
• DataTypes Schema Collection - could be moved to /docs/

The wiki predates https://mysqlconnector.net/ as a documentation site. Instead of having documentation in two places, it should be consolidated into /docs/ and the entire wiki deleted (which will declutter the top nav bar in this repo).

• Concurrency Benchmark Results - has been deleted
• Schema Collections Supported by GetSchema - moved to https://mysqlconnector.net/overview/schema-collections/

Disabled the wiki for this repo (without moving the DataTypes Schema Collection page to a new location).
