feat: robust handling for internal uri

[SH4LIN]

What

• This PR will allow developers to individually specify the home URL and site URL.
• This PR will add wrapper functions to identify internal URLs more robustly
• This PR will replace the internal URL with the NextJS app URL using JS URL API instead of simple string replace.

Why

• Current approach for the replace is prone to bugs.

Related Issue(s):

• Part of https://github.com/rtCamp/headless/issues/413

How

• We will parse the URL using the URL JS API and replace the properties with the nextApp url properties and build the URL again from it.

LGTM.

The env vars for CI/CD are needed to be updated.

These are comments from an old code review. Not sure why they didn't get shared w. The rest, nor if they're still accurate 🤦‍♂️

I'll re-rereview tomorrow night

[justlevine]

Last round of feedback from me (hopefully)

If @ayushnirwal has no suggestions for a utils naming convention, then I'll see what GPT recommends

@Ta5r can you PTAL at the changes to the env variables (both documented and the comments that get output in the .env.example), and make a matching PR for snapwp-helper?

[justlevine]

Can be merged after @Ta5r updates the env vars in rtcamp/snapwp-helper
