#49741

Why

Following PR for #50309, this PR focus on implementing cross dag run task group detail page

How

• implement for cross dag run
• add group breadcrumb

Note

Task group can't be fetch by getTask and thus I use the grid endpoint to get task group in Task component following Brent's suggestion in #49741. Not really sure what info should be display on the group task header, thus please let me know if the header need any change. Thanks!
