[BUG] ROOT_URL variable is not respected in hyperlinks from home page

[aadibajpai]

If you're at https://aadibajpai.com/blog/ and you try clicking on any of the links in the ToC then they will be broken, but if you open the post and then navigate then they'll work as expected.

I assume this one is as simple as inserting that ROOT_URL variable wherever the toc generation takes place 🤔

Looks like it's not respected from the "All Posts" page either https://aadibajpai.com/blog/posts/index.html, all links from here are broken

same for https://aadibajpai.com/blog/tags/index.html, I think the issue is that no ROOT_URL is present in https://github.com/pastly/bm/blob/master/internal/globals.sh#L183 and https://github.com/pastly/bm/blob/master/internal/globals.sh#L241
