Scoped label display and documentation tweaks (#23430)

Browse Source 
* Fix scoped label left and right part breaking across lines.
* Remove slanted divider in scoped label display, make it straight.
After using this for a while, this feels more visually noisy than
helpful.
* Reduce contrast between scope and item to reduce probability of
unreadable text on background.
* Change documentation to remove mention of non-exclusive scoped labels.

For organizations, you can define organization-wide labels that are shared with all organization repositories, including both already-existing repositories as well as newly created ones. Organization-wide labels can be created in the organization `Settings`.
Labels have a mandatory name, a mandatory color, an optional description, and must either be exclusive or not (see `Scoped labels` below).
Labels have a mandatory name, a mandatory color, an optional description, and must either be exclusive or not (see `Scoped Labels` below).
When you create a repository, you can ensure certain labels exist by using the `Issue Labels` option. This option lists a number of available label sets that are [configured globally on your instance](../customizing-gitea/#labels). Its contained labels will all be created as well while creating the repository.
## Scoped Labels
A scoped label is a label that contains `/` in its name (not at either end of the name). For example labels `kind/bug` and `kind/enhancement` both have scope `kind`. Such labels will display the scope with slightly darker color.
Scoped labels are used to ensure at most a single label with the same scope is assigned to an issue or pull request. For example, if labels `kind/bug` and `kind/enhancement` have the Exclusive option set, an issue can only be classified as a bug or an enhancement.
The scope of a label is determined based on the **last** `/`, so for example the scope of label `scope/subscope/item` is `scope/subscope`.
Scoped labels can be marked as exclusive. This ensures at most a single label with the same scope is assigned to an issue or pull request. For example, if `kind/bug` and `kind/enhancement` are marked exclusive, an issue can only be classified as a bug or an enhancement.
