chore(e2e): add manual override for networking in Linux

[robertwilde]

When setting up Playwright tests in Windows using WSL, I found that the docker container has trouble connecting to localhost:4200. To be able to pass another address a slight change needs to be made to e2e-local.sh

Code Review

This pull request aims to allow overriding network settings for e2e tests, particularly for WSL users. The change in e2e-local.sh attempts to set default values for LOCAL_ADDRESS and NETWORK_MODE on Linux only if they are not already set. However, the current implementation has a flaw that causes it to break the existing configuration for Linux. I've left a comment with a suggested fix to correctly implement the intended behavior while staying within the scope of the change.

[gemini-code-assist]

The current logic for setting default values for LOCAL_ADDRESS and NETWORK_MODE on Linux is not working as intended. These variables are initialized on lines 33-34, so the [ -z ... ] checks on lines 39 and 42 will always evaluate to false. This results in the Linux configuration incorrectly using the default bridge network mode and $BRIDGE_ADDRESS instead of host and localhost, which is a regression from the previous behavior.

To correctly allow overrides while setting Linux-specific defaults, you could instead check if the variables still hold the initial non-Linux default values and then replace them. This ensures that user-provided overrides are respected.
