fix(angular): allow float strokeWidth (and size)

[undsoft]

closes #4287

Description

Allows strokeWidth to be specific as float string, e.g.:

<svg lucideStar strokeWidth="1.2" />

Previously this would get interpreted as 1.

Note. This also allows size to be specified as float, which is not useful.
But I thought that there is no harm in that, so I didn't guard against it.

Hey @undsoft,

As far as I can tell, this behaviour will already get resolved and then some more by #4253, which @swastik7805 unfortunately closed without further notice. I've reopened that PR and reverted the requested unwelcome changes to the lucide-react codebase, I'd much appreciate if you could review the changes there and see if you find them satisfactory. 🙇‍♂️
