After merging the old personal gem5 repository with the stable version
v24, I tried to run the project inside the `.devcontainer` environment.
During the image build process, I encountered the following error:
```sh
[7683 ms] Start: Run in container: /bin/sh -c ./.devcontainer/on-create.sh
fatal: detected dubious ownership in repository at '/workspaces/gem5'
To add an exception for this directory, call:
git config --global --add safe.directory /workspaces/gem5
[7724 ms] onCreateCommand failed with exit code 128. Skipping any further user-provided commands.
```
This error occurred due to an ownership permission problem, which I
resolved by adding the following line.
