Adding this doesn't really help though. `stable-7648-2` is broken
regardless. `stable-7648-3` is necessary to make it work.

We're already updated to `-3` anyway. This just adds the missing
environment variable for completeness.

This reverts commit 2c01c5bedf.

We don't really fix these, but just suppress them,
because they're like that intentionally.

We try to name variables in a way that is consistent with the
configuration key they control. If the upstream component uses
camelCase, we also need to include camelCase in the variable name.

fixes spantaleev/matrix-docker-ansible-deploy#1889

Support for arm64 images tracked in jitsi/docker-jitsi-meet#1214 and added in jitsi/docker-jitsi-meet#1269

Tested, works without any configuration changes.

As of docker-jitsi-meet stable-6433 [1], `/config/interface_config.js`
is regenerated on every boot. The correct way to modify the interface
config is now via `/config/custom-interface_config.js`, which is
appended to a default copy of `interface_config.js` by
`/etc/cont-init.d/10-config` on every boot of the docker image.

Given that `interface_config.js` is considered deprecated by upstream
(all options will eventually be moved to `config.js`), we also deprecate
the `matrix_jitsi_web_interface_config_*` variables in favour of
`matrix_jitsi_web_custom_interface_config_extension`.
