fix: Livechat widget connecting to localhost instead of actual site url

Proposed changes (including videos or screenshots)

Issue(s)

https://rocketchat.atlassian.net/browse/CTZ-272

Steps to test or reproduce

Basically, since we changed how settings are initialized on #34199, the file that "obtained" the server url to preppend to the livechat widget chunks was using the localhost url (default) instead of using the url the server was changed to.
This fix should allow it to be more reactive and change everytime the server url changes by just refreshing the widget on browser.

Can we have a test for this?

[KevLehman]

It would be nice, but actually apart from some units i dont see much value 🤔 and even units, i dont see much value either cause the function is just 2 lines...

but if u want, i can try to add some.

It’s not something I want to insist on, but since this is a fix, we should include a test to ensure it doesn’t break again in the future.

[pierre-lehnen-rc]

Note: the unit tests on this PR simply check if the function that replaces URLs is replacing with the right value, assuming a valid input.

It doesn't check if the actual file gets replaced properly - but if that were to fail, then the existing tests would catch the problem already.

The existing tests didn't catch this bug because all of our CI and development environments run in the localhost URL which is used by default before the settings are loaded. Maybe we should have at least some testing environments run on a custom URL...
