OpenGL core spec 4.5 page 4 specifies:

"The core profile of OpenGL 4.5 is also guaranteed to support all previous ver-
sions of the OpenGL Shading Language back to version  1.40. In some implemen-
tations the core profile may also support earlier versions of the OpenGL
Shading
Language, and may support compatibility profile versions of the OpenGL Shading
Language for versions 1.40 and earlier. In this case, errors will be generated
when
using language features such as compatibility profile built-ins not supported
by the
core profile API.  The #version strings for all supported versions of the
OpenGL
Shading Language may be queried as described in section 22.2."

But I think the above version returns 0 in cases where you request a glsl
version that is lower and not a list of supported glsl versions like the
function below:
