doc: fix PDF with greek letter

For an unknown reason, the sign "μ" is not accepted by some environments,
probably due to the version of some Latex packages or dependencies.

	! Package inputenc Error: Unicode character μ (U+03BC)
	(inputenc)                not set up for use with LaTeX.

It is fixed by installing texlive-langgreek.
