How does one increase the timeout for the JSON Ledger API in Canton 3.x?

Timed out getting completion for submission
with userId=*** , commandId=***, submissionId=***.
The submission might have succeeded or failed,
but it couldn't be determined in time.

With the following configuration…

canton.participants.<participant name>.http-ledger-api.server.request-timeout

…introduced here:

Configure this value to allow
more complex Ledger API requests to complete
(e.g. /state/active-contracts).
The default value is 20 seconds.

For the Splice bundle, this configuration can be set as an ADDITIONAL_CONFIG environment variable:

- ADDITIONAL_CONFIG_JSON_API_TIMEOUT=
    canton.participants.participant.http-ledger-api.server.request-timeout=60s
