Support QML styles (Vector layer added via Layman is not styled)

Feature Request

Is your feature request related to a problem? Please describe.
Related to #3440
Adding a vector file (GeoJSON) with style file directly into a map is OK. Adding a vector file (GeoJSON) with style file while also publishing the layer into Layman results into a layer without styling.

Describe the solution you'd like
Also load layer's styles from the Layman.

Describe alternatives you've considered
none

Additional context
spin-off from #3440

@jmacura what is the style definition for that layer in layman in this case? Is it empty or could it be in SLD 1.1 format maybe?

[jmacura]

@raitisbe I have tested now with SLD 1.0 and the styles were loaded indeed... 🤔

cf. https://hub.lesprojekt.cz/rest/workspaces/macurajan/layers/zones

So, yes, the issue might be related to SLD 1.1 or QML.
@fzadrazil Do you have any specific use case when the style upload fails, which you could share with us?

@jmacura Please check if #3616 solves it

Problem is with QML styles.

[jmacura]

We already support QML styles (cf. #3435). Seems like the QML file structure has changed recently and it is not yet reflected by geostyler-qgis-parser.
