fix(core): increase max event listener count (#5889)

Some users with very large projects occasionally run into a
"maximum event listeners exceeded" warning. It's not quite clear why
this would happen, but maybe this is to be expected for larger projects.

Raising the limit should be harmless, and might help reveal underlying
issues with the event listener lifecycle.
