Suggestion: Do not require login for connects.brainlife.io landing page

[kabilar]

Hi brainlife team, when I go to https://connects.brainlife.io it redirects me to https://connects.brainlife.io/dashboard and I see the message below:

If I stay logged out, other pages are still open-access. So perhaps https://connects.brainlife.io should redirect to https://connects.brainlife.io/projects, which would mirror the behavior on the brainlife portal. And then the user can log in for the restricted access pages. Thank you.
