feat(issue-details): remove browser context for some nextjs runtimes (#62278)

this pr removes the browser context for non-browser runtimes on events
from the nextjs sdk. for these server errors, we don't need to show the
browser as the first context with an icon, and now it is much more clear
where the error is happening. if a user wants to know this information,
they can still find it in the tags.
