[Bug] The CC Vocabulary is not being used

## Description
After looking at fairly new merged pr #122, where instead of using the Vocabulary CDN, the entire `global-header` component has been hard-coded in.

## Expectation
The Vocabulary CDN (for styles & scripts) should be imported in, over having them hard-coded in. As this will help follow the standards & guidance of Open source CC, also maintaining the repo will be ez!
This will fix many other issue that have been raised over time, regarding buggy UI.

## Environment

- Device: Laptop
- OS: Ubuntu
- Browser: Chrome
- Version: 99.0.4844.84

## Additional context
Importing them directly will make considerable changes, as it would try to overwrite the existing CSS, will have to fix them. The best way to fix this would be to import them in, and then remove the CSS that gets overwritten. Also, I would like to work on this issue.

## Resolution

- [x] I would be interested in resolving this bug.
