[FIX] Permission view-all-teams is not checked in the teams.info endpoint

[LucianoPierdona]

Proposed changes (including videos or screenshots)

Previously any authenticated user was able to access the teams.info endpoint, this PR updates this so only users with the view-all-teams permission or team members can access it.

Issue(s)

Steps to test or reproduce

User 1

• Create a private team with only User 1 added to it.

User 2

• Access the above team through curl

curl  -H "X-Auth-Token: {authToken}" \
      -H "X-User-Id: {userId}" \
      -H "Content-type: application/json" \
      http://localhost:3000/api/v1/teams.info?teamName=Team1

Expected result

• If User 2 doesn't have the view-all-teams permission, the response must be unauthorized;
• If User 2 has the view-all-teams permission, the response must be succesful;
• For User 1, the response must be succesful;
• If the team is changed to public, the response must be succesful for User 1 and User 2 regardless of the view-all-teams permission.

LGTM. We just need a review from the chat-engine team for the new tests.
