docs: combine validation test bind and ingest tables

[amoeba]

What's Changed

• Renames the headers for the tables to be simpler: Just "$VENDOR_NAME to Arrow" and "Arrow to $VENDOR_NAME"
• Combines the bind and ingest type mapping tables into one.

Closes #107

Three things:

1. I still want to figure out how to colspan=2 when both types are the same
2. This exposed one issue I need to look at: For "float" in the Arrow to MySQL table, we have no result for Ingest so this currently shows "None"
3. I also want to improve the combined table headers, I think I can do that when I do 1.

Using a list-table and just handling the case where the types aren't the same is pretty readable. Here's what that looks like changed:

👍 That seems like a good workaround if there's no clean way to do colspan=2.

You can just directly generate HTML instead of relying on list-table if you want colspan. You may have to manually add the necessary CSS classes to satisfy the material theme.

I just went with raw HTML but was able to get something reasonable, see https://69211407df11503fc41bccc3--vermillion-kringle-ffe824.netlify.app/drivers/mysql/#arrow-to-mysql.

I should set the jinja2 option that automatically collapses spaces so that we don't have to fiddle with - all the time
