docs: sync tls.crl_file into duplicated TLS tables

[eschabell]

• Add tls.crl_file to the TLS property tables on s3, opentelemetry
  (input and output), azure_kusto, forward, and tcp-and-tls, using the
  canonical wording from administration/transport-security.md
• Sync the reserved config key list for Go output plugins with the
  properties flb_output.c actually reserves, adding tls.ciphers,
  tls.crl_file, tls.max_version, tls.min_version, the tls.proxy.*
  family, tls.verify_hostname, and the tls.windows.* family
