Add note about environment name to Deployment Frequency charts
What does this MR do?
Updates the Deployment Frequency charts to include a note that the name of the environment must be production in order for its deployments to show on the graphs. A link to the documentation is also included.
This text will be updated when this naming restriction is changed/removed (see #296849 (closed)).
Proposed text
Proposed text from @ngaskill (see #299353 (comment 491174890)):
These charts display the frequency of deployments to the production environment, as part of the DORA 4 metrics. The environment must be named
productionfor its data to appear in these charts. Learn more.
