Make l. alias look as nice as other eza aliases

[sliva0]

Updates l. alias to pipe its output back into eza (with -d flag to not look into directories), so it will show filtered files and dirs in the same nice format with metadata as other eza aliases.

--dereference flag is needed so eza will not try to print where symlinks point to after -> symbol, as this would break second eza call (related eza issue).

Illustration for the difference this change makes (before/after):

Would it be more concise/readable to use eza's builtin --ignore-glob flag?
To my knowledge this does the same thing:

eza -al --ignore-glob '[!.]*'
