feat(integrations): extra life variables

[Firebottle]

Handles #2229

Description of the Change

This adds several new variables specifically for extra life. All of these have a "easy mode" where it'll just output a string with the information for easy display. However, you can also pass an argument to just get the JSON back for advanced usage.

extraLifeInfo = allows a user to basically get any extra life profile info. This includes things like goal amounts, avatarURL, etc.
extraLifeMilestones = allows the user to get milestone information.
extraLifeDonations = allows the user to get donation information.
extraLifeIncentives = allows the user to get incentive information.

Applicable Issues

• All of these work, but I believe milestones and incentives could be made much better than what I have here.
• The node module has a "where" filter in it's docs, but I could never get a call to go through using it. If we could figure that out the code could be simplified quite a bit.

Testing

Chat commands with each of these variables.

Awesome work on this!!

I would suggest an organizational tweak: move these variables into the /integrations/builtin/extralife area and have the extralife integration register them on init (similar to how the other integrations do with their effects & variables)

Additionally, as a quality-of-life improvement, we can take advantage of the participant ID that the users already provide in Settings > Integrations > ExtraLife so they don't have to provide it for every $variable. I think being able to provide a custom ID is cool, so perhaps we make the participant ID the last argument of each variable, making it easier to have it be optional and default to configured participant ID.

You can get the configured participant ID like so:

if (!participantId) {
    participantId = integrationManager.getIntegrationAccountId("extralife");
}
