feat(onboarding): refetch integrations query on project creation tab refocus

[ameliahsu]

refetch the messaging integrations API query when the project creation page is refocussed

this is really only for the edge case where someone installs an external installation (MS Teams), in which case we don't know when the installation has completed so we can't automatically refresh

I suggested to @ameliahsu that we do this on page re-focus using react-query instead. Since the edge case where they go and add an integration will mean they have to leave the page focus and come back
