DOP-4282: Implement container for lab drawers

[rayangler]

Stories/Links:

DOP-4282

Current Behavior:

Server prod

Staging Links:

Server staging with drawer - notable difference is that the lab opens in a drawer instead of as part of the docs content.
Server staging without drawer

Notes:

• The purpose of this PR is to create a component that renders the Instruqt lab in a drawer. Finalized styling for the lab title and the lab buttons are excluded and will be addressed as part of DOP-4283.
• Since the interactive lab button does not exist next to the page heading yet, the drawer will be shown in place of the embedded Instruqt lab as long as the feature flag is turned on. This will be reconciled as part of a future PR.
• Any merge conflicts will need to be sorted out to be compatible with DOP-4280: Create React context to manage Instruqt lab state #989, once it is merged.

LGTM once DOP-4280 is pulled in! It's been merged

I think we might also want to import and use the hasLab variable from InstruqtContext as part of the conditional here

Yup, for sure. Forgot that from the context merge. Thanks for catching!
