Modify styling of CLI output

[zionts]

Specifically, replace all instances of chalk.blue with chalk.cyan, which
is more readable in dark mode (the green color we use is basically
unreadable in light mode anyway)

Additionally, this changes some spacing of the service:list command to
allow users to see the URL to navigate to more obviously.

TODO:

• Update CHANGELOG.md* with your change (include reference to issue & this PR)
• Make sure all of the significant new logic is covered by tests
• Rebase your changes on master so that they can be merged easily
• Make sure all tests and linter rules pass

*Make sure changelog entries note which project(s) has been affected. See older entries for examples on what this looks like.

I think the only concerning thing is that the cyan is less visible on a white bg, than the blue. But I think the cyan-white combo is more visible than the blue-black combo, and since the majority of people use dark terminals, I think this is an okay tradeoff.

Just a couple screenshots to show the differences here :)

thanks for attaching the screenshots @JakeDawkins ! Maybe @daniman wants to mess around with colors too 👀

[JakeDawkins]

@zionts @daniman maybe a solution would be to use background colors in tandem with foregrounds? that way, we know the background color and the foreground color so we don't run into any theme issues with terminals? Just a thought, it could look clunky

[zionts]

@JakeDawkins I found that background colors looked super clunky, unfortunately :/ Ideally, there'd be a library that takes into account the users' theme, but in lieu of that, I think this is an improvement!

@zionts gotcha, gotcha. I think another alternative is to try to set colors as best as we can, but allow a --noColor or -n flag to disable colors and instead set the text to bold for users whose themes are still unreadable.

I think since people can adjust their color palettes all over the place, we may not be able to fully ensure readability.
