Check ChainSpec consistency with upstream config.yaml (#9008)

Closes:

- https://github.com/sigp/lighthouse/issues/9002


  - Commit `config.yaml` for minimal and mainnet to `consensus/types/configs`. For now we omit any auto-downloading logic, to avoid the hassles of dealing with Github rate limits etc on CI. Unfortunately these files are NOT bundled inside the spec tests.
- Fix the values of `min_builder_withdrawability_delay` for minimal and mainnet. These discrepancies aren't caught by the current spec tests, because the spec tests are missing data: https://github.com/ethereum/consensus-specs/pull/5005. Will be fixed in the next release/when we update to nightly.
- Fix the blob schedule for `minimal`, which should be empty, NOT inherited from mainnet.
- Keep `SECONDS_PER_SLOT` for now because the Kurtosis tests fail upon their complete removal. We will be able to completely remove `SECONDS_PER_SLOT` soon.
