#339 Add information about web server configuration

[DanieliMi]

Description

As mentioned in #339 the MFTF doesn't support executing CLI command if the web server points to <MAGE_ROOT_DIR>/pub as recommended in the DevDocs. I added information about it in the docs. It is not mentioned currently and might save other developers some time figuring it out (it would've saved me some time).

@dobooth Please review from DevDoc side. And do you need PR to master?

[dobooth]

Thanks for the contribution, @DanieliMi. We need documentation PRs to point to master, so they can get picked up by our automation systems. Can you please update and rebase this PR to master? Thanks!

[DanieliMi]

@dobooth Shall I force push the rebase or create a new branch from master, cherry pick the commits and open a new PR? The problem is my patch branch is from develop.

[dobooth]

@DanieliMi It probably better to make a new branch from master and cherry pick.
