Label merging should be solely text-based

[aplavin]

Labels with the same text do not get merged:

scatter(rand(100), label="Abc" => (;markersize=20))
lines!(rand(100), label="Abc")
axislegend(merge=true)

To get merged, the same label arguments need to be specified, even if they don't make any sense for the plot type:

I guess merge=true is supposed to merge labels based on their text, not on their attributes – right?

• what version of Makie are you running? (]st -m Makie) v0.21
• can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie)
• What platform + GPU are you on? any

Yep that's a bug, should add a test case for this scenario
