Remove the Uuid test seam from public constructors #1561

What happens

Three public constructors take a Uuid parameter that exists only so tests can inject deterministic names:

• new Network(uuid?)
• new DockerComposeEnvironment(composeFilePath, composeFiles, uuid?)
• new GenericContainerBuilder(context, dockerfileName, uuid?)

It is the reason Uuid, RandomUuid and randomUuid are exported from the package. For Network it is the only constructor parameter, which takes the slot that real options would use.

Expected

Public constructors take only user-facing arguments. Tests get deterministic names another way, for example a withName/withProjectName style setter or an internal factory.

Where

• packages/testcontainers/src/network/network.ts
• packages/testcontainers/src/docker-compose-environment/docker-compose-environment.ts
• packages/testcontainers/src/generic-container/generic-container-builder.ts

Notes

• Removing a constructor parameter and the Uuid exports is breaking, hence major.
• DockerComposeEnvironment already has withProjectName, which covers its use of the seam.

Dependencies

• Blocked by Support network options on Network #1535: Network needs a real way to set a name before its only constructor parameter is removed.
