fix: add id and resume parameters to SwanLab integration

[thecaptain789]

Fixes #43698

Adds support for run resumption in the SwanLab integration via two new environment variables:

• SWANLAB_RUN_ID: Unique identifier for the run
• SWANLAB_RESUME: Controls resumption behavior (must, allow, never, auto)

This allows users to resume training runs when using Trainer.train(resume_from_checkpoint=...) without SwanLab creating a new experiment.

Example usage:

export SWANLAB_RUN_ID="my-run-id"
export SWANLAB_RESUME="allow"
python train.py --resume_from_checkpoint=./checkpoint
