Parse requirement's alias and display "alias(name)" if 'alias' not empty

[horacimacias]

This allows for charts using dependencies to have documentation showing their aliases (if defined).
This is handy when several dependencies use the same chart with different aliases.

Before

Repository	Name	Version
repo	dependency1	0.1.0
repo	sharedchart	0.1.0
repo	sharedchart	0.1.0
repo	sharedchart	0.1.0

after

Repository	Name	Version
repo	dependency1	0.1.0
repo	dependency2(sharedchart)	0.1.0
repo	dependency3(sharedchart)	0.1.0
repo	dependency4(sharedchart)	0.1.0

Thanks a lot for the change @horacimacias! Sorry it took me so long to look at it.
