change .eslintrc to .eslintrc.js (teambit#8297)

It fixes the error shown locally:
```
Oops! Something went wrong! :(

ESLint: 7.32.0

Error: Cannot read config file: /Users/davidfirst/teambit/bit/e2e/.eslintrc
Error: Function yaml.safeLoad is removed in js-yaml 4. Use yaml.load instead, which is now safe by default.
