Use a unique 'title' string in info.html

[wfjm]

I'm using KiCad 5.1.5 as it comes with Ubuntu 20.04 LTS.
I've copied the AISLER-2Layer and AISLER-4Layer templates to ~/kicad/template.
The File -> New -> Project from Template dialog shows in the tab User Templates two templates. both named AISLER.

It turns out that the value of title from meta/info.html is used, which is for both templates

  <title>AISLER</title>

I've changed them to AISLER-2L and AISLER-4L, now I get unambiguous entries in the selection box.
Minor and trivial change, but I think that the title strings should be unique across all offered templates.
