Fix infolist entry label

[zepfietje]

Description

Infolist entries of nested relationship attributes currently get a wrong label which is different from what a table column with the same name gets.

	Column/entry name	Table column label	Infolist entry label
Before this fix	generation.project.team.name	Team	Generation
After this fix	generation.project.team.name	Team	Team

Functional changes

• Code style has been fixed by running the composer cs command.
• Changes have been tested to not break existing functionality.
• Documentation is up-to-date.

BC, also inconsistent with schema component labelling. In v4 these will be the same algo. I think table cols and infolist entries deserve different labels since entires go into much more depth and there could be more than one entry for the same relationship. Also JSON entries?

I don't think this is a breaking change, rather a bug fix.

Which algorithm will be used in v4?

Personally I don't see why infolist entries and table columns are named inconsistently.
I do understand your remark about JSON entries, but still then the algorithm in this PR could work fine for most cases. Even if it didn't work correctly for JSON, usage of relationships is generally much higher than JSON fields I think.
