Builds for Debian 11 and 12 are broken

[rwlodarczyk-xealth]

For Debian 11, I get: E: Unable to locate package openresty
For Debian 12, I get: E: Version '1.21.4.3-1~bookworm1' for 'openresty' was not found

However, when performing an apt search openresty, the package is shown:

...
openresty/unknown 1.21.4.3-1~bookworm1 amd64
  core server of OpenResty for production use
...

Even an apt-get install openresty gives an error:

This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'openresty' has no installation candidate

Hmm, this seems to be specific ONLY building on Macs with M1/2/3. Probably my build string is wrong because of architecture differences (e.g. arm64 vs amd64).

Yes, it is that. See the .travis.yml for examples:

docker build  --build-arg RESTY_APT_REPO="https://openresty.org/package/arm64/debian" --build-arg RESTY_APT_ARCH=arm64 -f bookworm/Dockerfile .
