[Infra] Fix failing test by changing read role permission (#205707)

Closes #203740
## Summary

This PR fixes failing test by changing read role permission to include
`streams` and `apm`. As I mentioned in this
[comment](#203740 (comment))
I saw some 403 errors related to some `streams` and `apm` APIs requests
so this should fix the test as it was meant to test if the dashboards
tab behaves correctly based on the admin/read-only role.

However, we should think about a solution to those errors in case we
have this scenario (read-only user role without apm/streams access) and
have a better error message/explanation of what is missing instead of
only showing the error toasts - I saw that we reverted
(#202418) already a solution
(#200151) for APM because of
other issues but now that we also include the `streams`
(#200060) (not sure if we need to
do the request in infra but that's probably a different discussion) it's
something we can revisit at one point to improve the user experience.
