Update for MySQL Connector/ODBC 8.0.11 - Tableau & C Auth

There are a couple of problem with the current documentation:

1. Connect From Tableau, under prerequisite, the link "The MySQL ODBC driver" will lead you to install the default GA version 8.0.11 of the MySQL Connector/ODBC. This has been tested as not working, so we should specify to click on "Looking for previous GA versions?" and download version 5.3.10 of the Connector/ODBC which is tested as working. Also, instead of saying "The MySQL ODBC driver" can we use the name "MySQL Connector/ODBC" to generate less confusion?

2. Under Install the C Authentication Plugin, the docs say to install the MySQL 5.7.x installer. Would be better to link to both the "MySQL Connector/ODBC" and the "My SQL shell" for simplicity? The installer has other options/components that are not necessary.
