[Issue 938] Make opportunity endpoints v0 instead of v1

[chouinar]

Summary

Fixes #938

Time to review: 5 mins

Changes proposed

Modified our opportunity endpoints to be prefixed with /v0 instead of v1

Context for reviewers

This was a recommendation we received to make clear the endpoints are early alpha versions. Also added a small description to the endpoints to help make this clear too.

Additional information

[acouch]

(praise) Awesome, to get this done so fast.

(suggestion) Adding

    app.title = 'Simpler Grants API'
    app.version = 'v0'
    app.config['DOCS_FAVICON'] = 'https://simpler.grants.gov/img/favicon.ico'

to src/app/config.py

would update the HTML title and version next to the title as well:

to:

Additionally, updating the app.info.description to "Back end API for simpler.grants.gov. This API is in ALPHA VERSION! Its current form is primarily for testing and feedback." would help communicate the state of the API as well.

Is this YAML file autogenerated before it's checked into git? (Sorry I'm not familiar with how our system currently works on this front!)

[chouinar]

Yes, there is a github action that runs automatically to do it. I just made a few updates based on what Aaron suggested, and it triggered: https://github.com/HHS/simpler-grants-gov/actions/runs/7387946234/job/20097725000?pr=939 which added this commit: 759df0f

Note, the yml file is not used by the API and is just reference. The file it uses when running is generated when the app starts up (exact same underlying code generates them).
