fix: jobs vulnerability

jobs depends on the `api` package to make request to render api
This package suffers from a vulnerability of one of its dependency,
specificcally the lodash.setWith package which is actually deprecated
There is a PR open for `api` to use full lodash instead of per method
packages (which are deprecated) but it has been merged yet.
This commit replaces the `api` package used to generate a render sdk from
their openapi spec by a home-made RenderAPI class
