File containing environment variables to be passed to the mautrix-signal service,
in which secret tokens can be specified securely by defining values for e.g.
`MAUTRIX_SIGNAL_APPSERVICE_AS_TOKEN`,
`MAUTRIX_SIGNAL_APPSERVICE_HS_TOKEN`,
These environment variables can also be used to set other options by
replacing hierarchy levels by `.`, converting the name to uppercase
and prepending `MAUTRIX_SIGNAL_`.
For example, the first value above maps to
{option}`settings.appservice.as_token`.
The environment variable values can be prefixed with `json::` to have
them be parsed as JSON. For example, `login_shared_secret_map` can be
set as follows:
`MAUTRIX_SIGNAL_BRIDGE_LOGIN_SHARED_SECRET_MAP=json::{"example.com":"secret"}`.
