ENH: project level cell output scrolling frontmatter

[bsipocz]

Proposal

It would be lovely to be able to project level opt in having the scroller enabled for all cell outputs. We added this functionality recently to the JB1 stack in this PR: executablebooks/MyST-NB#683

Additional notes

See this cell level enhancement that paves the way to get this added to the project level: #2433
