🐛 Add trailing slash to event endpoint to return gif in response to GET request

[tygavin]

Minor update for console warning.

The trailing / included in the collect.tealiumiq.com endpoint will ensure an "image/gif" HTTP response instead of the current "application/json" response.

The current application/json response resulted in console warning messages when the browser is looking for a response that has Content-Length greater than 0. This fixes the warning message.

@jeffjose A minor update for Tealium requires review. Thanks for your help.

[jeffjose]

LGTM from my side. Over to @lannka for approvals.

• The change looks fine.
• @tygavin previously added Tealium to AMP in this pr
• I have not been able to trigger this endpoint on real sites but the endpoint returns html/gif response.

Overall LGTM.

@lannka or @zhouyx: Do you mind merging. I technically can but since you are the owners, I don't want to step on your toes.

thanks Avi

Thank you @avimehta!

@rcebulko another question, can we keep Avi as the owner but not having the owner bot automatically request reviews from them. Otherwise they'll get a lot of review requests 😈

[rcebulko]

You can prefix his username in the OWNERS.yaml file with ?, ie. - "?avimehta" and he will never be automatically requested as reviewer.

Thanks! Will summit a PR.
