Update repo and branch configurations in workflows

Updated the `repo` and `repo-tag` values in the `build-cimgui` job:
- Changed `repo` from `JunaMeinhold/cimgui-` to `cimgui/cimgui`.
- Changed `repo-tag` from `docking_inter` to `conv2`.

Modified the `pr-base-branch` in the pull request workflow:
- Changed from `"main"` to `"arm-abi-patch"`.

These changes align the workflows with the new repository and branch
configurations for building and pull request management.
