Why I did it
In latest syncd container, it is installed bullseye, can't find command '/usr/bin/python'.
Some scripts such as test_copp still calls /usr/bin/python in syncd.
Submitted the change in #11807 for syncd docker, but it's better to add it in bullseye base docker.
How I did it
Install python-is-python3 package in bullseye base docker to resolve this issue, whatever run python or python3, it will run /usr/bin/python3, will not cause the error of can't find command '/usr/bin/python'
How to verify it
run python in syncd container.
