#35 Add interactive text and website links for hotlines

[lizzthabet]

@jaqarrick and I made progress on issue #35. This PR adds interactive icons for website and text for each hotline entry that has that information available. It doesn't include any work related to tags (which are also mentioned in #35).

• Display the text contact information underneath each hotline entry that has text info
• Updated constants/PhoneNumbers to store text information in an object with content and number properties, instead of a string
• Add IconGroup component that's responsible for rendering phone, text, and website icons that link to the corresponding url

View from iOS simulator:

View from messages app on desktop after clicking sms link from web app:

We tested in browser and Expo Android app without any issues. The iOS simulator had a couple bugs: phone number links (whose implementation didn't change in our code) threw an error; and sms texting links opened up in the messages app with the appropriate content, but not the appropriate phone number. After googling for a bit, our best guess is that both of these issues are due to limitations in the iOS simulator and not with the tel or sms links.

This is our first time contributing to this project, so feel free to let us know if there are any code style or implementation details that can be approved or better aligned with existing patterns!

A couple additional questions:

• [ ] Should the website url be listed as text, like the phone numbers, in addition to being linked with the website icon?
• [ ] Is there a better way to test on iOS devices?
