Eval more model, control randomization & auto read webpage via workflow

- Control auto read webpage via eval workflow. Prefix env var with KHOJ_
  Default to false as it is the default that is going to be used in prod
  going forward.

- Set openai api key via input param in manual eval workflow runs
  - Simplify evaluating other chat models available over openai
    compatible api via eval workflow.
  - Mask input api key as secret in workflow.
  - Discard unnecessary null setting of env vars.

- Control randomization of samples in eval workflow.
  If randomization is turned off, it'll take the first SAMPLE_SIZE
  items from the eval dataset instead of a random collection of
  SAMPLE_SIZE items.
