Change destination for shortened links

[bondz]

The shortened bit.ly links in the project would not redirect to the website since bitly doesn't let users except enterprise users change the destination of links.

This poses a problem for all the shortlinks that are already in the wild, as all of them would now redirect to https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/template/README.md

We have a few options, switch to a service that lets us edit the destination of shortlinks, like

page.links or rebrandly

This still leaves us with problems like in #5497

Second, we could document in the readme the new destination for the links, this would help the more than 4k people who clicked on the PWA link alone this month.

Does bit.ly have an open source plan? 😀

Since these links are already out there and we can't really change them maybe we should just have placeholders for them in the README. Then the link still works and we can just point them to the corresponding page in the new docs.

I'm sure an email to them could get this straightened out. 😄

[bondz]

They don't currently have an open source plan. An Enterprise plan is the only listed paid plan they offer.

Reaching out to them also doesn't hurt.

[Timer]

@bondz could you reach out since the link (I assume) is associated with your account?

[bondz]

@Timer yes, I would. Maybe I could copy you in the mail?

[Timer]

Sure you can copy me!

[bondz]

Sent the mail to @bitly still waiting for a response.

More broken shortlinks here: #5617.

This is increasingly going to affect a lot of users and I've not gotten any response from @bitly. We could proceed to change the URLs for new versions. cc @Timer
