Ballerina Docker Run Command Should be Able to Run Without Root Permission

[ThisaruGuruge]

Description:

We can use the following command to build a Ballerina package:

docker run ballerina/ballerina:nightly bal pack

But when we run this command, the docker run have to have root permissions (AFAIU). We can provide -u 1000:1000 to the docker command, but this results in creating a directory named ? and inside that directory the .ballerina directory is created by the bal tool. Ideally this directory shouldn't be created.
