Add grouping for tags

**Is your feature request related to a problem? Please describe.**
When working on in a mono repository it is common to prefix all release tags with the project being released. Releasing a new version might require you to release a lot of sub packages meaning the tags count explode. This makes the menu hard to parse/read.

**Describe the solution you'd like**
Add grouping of tags (and maybe branches¹), enabled through some setting toggle.

The tags current could look like this
```
project/0.1.1
some_other_project/0.1.1
sub_project/0.1.0
project/0.1.0
some_other_project/0.1.0
```

I wish that it was collapsed into
```
project/
some_other_project/
sub_project/
```
To then see the tags that belongs to a group you would navigate into it (like what happens if you click Enter within [4] Commits)

For bonus points it would be awesome if you could see the latest tag easily maybe like this (with different colors)
```java
project/ (0.1.1)
some_other_project/ (0.1.1)
sub_project/ (0.1.0)
```

¹ If this is added for branches then maybe only branches of a certain age are grouped (maybe that's a different setting?). That way your common branches stay at the top but branches that are older are hidden to clean up the interface.
