Connector Generation - no templating

[mergebandit]

Describe the bug
In the (template readme)[https://github.com/apollographql/connectors-community/blob/main/connectors/.template/README] file, there's a placeholder for {{TEMPLATE}} (which is actually invalid syntax, as whats in there is actually {TEMPLATE}}.

It doesn't appear the (generator)[https://github.com/apollographql/connectors-community/blob/main/file-new/index.js] has any support for templating, or I'd fix this an offer a PR. Do you have plans for this?

To Reproduce
Steps to reproduce the behavior:

1. Execute npm start & fill out prompts
2. Newly created connectors//readme will have # {TEMPLATE}} REST Connector as the title

Expected behavior
The title will be updated to eg Heygen REST Connector

I actually didn't put a great "contributor" path in this, I have been working on that since you opened this issue. I'll have a branch for you to test out 🔜
