Fetch a `codecheck.yml` without aborting the whole render
Source:R/utils_preprocess_register.R
get_codecheck_yml_or_null.RdThe register is rendered from 130+ `codecheck.yml` files spread over GitHub, OSF, GitLab and Zenodo, and every one of them is a chance for a rate limit, an outage or a moved repository. A single such failure must degrade the one entry it concerns, not stop the render of all the others - so every enrichment loop below goes through this wrapper, which turns the error into a warning naming the certificate (`register_render()` collects and reports those at the end) and returns `NULL`, the same value the loops already handle for a repository without a `codecheck.yml`.
