* fix github service tests
* migrate some services from examples to openApi
* document latest variant with separate examples
making seperate routes for the /{version} and /latest variants
allows us to only show the docs for
- include_prereleases
- sort and
- filter
in the situation where they are relevant
* log to sentry if upstream service responds with 429
* allow services to decide which error(s) to log, default to 429
* don't log 429s from endpoint or dynamic badges
* supress 429s from uptime robot badges
* supress 429s from weblate if not calling default server
* cache opencollective badges for longer
* cache discord badges for longer
* cache github workflow badges for longer
* allow serviceData to override cacheSeconds with a longer value
* prevent [endpoint] json cacheSeconds property exceeding service default
* allow ShieldsRuntimeError to specify a cacheSeconds property
By default error responses use the cacheLength of
the service class throwing the error.
This allows error to tell the handling layer the maxAge
that should be set on the error badge response.
* add customExceptions param
This
1. allows us to specify custom properties to pass to the exception
constructor if we throw any of the standard got errors
e.g: `ETIMEDOUT`, `ECONNRESET`, etc
2. uses a custom `cacheSeconds` property (if set on the exception)
to set the response maxAge
* customExceptions --> systemErrors
* errorMessages --> httpErrors
* switch from github workflows to github actions workflows
* update github actions workflow badge to use api
* add test case for missing branch param
* custom deprecation message
