Help Wanted: Tables aren't consistently formatted

[cwarnermm]

The product docs source code uses a few different types of syntax for table-based content which applies inconsistent default CSS look & feel across the site.

Examples:

• https://docs.mattermost.com/about/faq-product.html#what-features-are-available-on-different-mattermost-clients
• https://docs.mattermost.com/configure/calls-deployment.html#modes-of-operation
• https://docs.mattermost.com/upgrade/important-upgrade-notes.html

Goal: Provide a standard way to display all table-based content site wide.

1. Investigate pros & cons of each approach.
2. Align on a single standard approach.
3. Work with UX to ensure that table formatting is sufficiently easy to scan/read, particularly in cases where tables are complex, such as the Important Upgrade Notes page.
