Add an ability to select a TypeDB version on an installation page

[izmalk]

Problem to Solve

Many commands to install TypeDB could be dependent on the TypeDB version.

Current Workaround

We write placeholders into the commands (like typedb-server-x.y.z), but that makes it impossible to just copy and paste the commands.

Proposed Solution

To have a drop-down list of TypeDB versions. Upon selecting one of the versions the content on the page will adjust (commands will change to accommodate the change).

Additional Information

For example, this command may change drastically for every version of TypeDB:

sudo apt install typedb-server=2.15.0 typedb-console=2.15.0 typedb-bin=2.12.0
