webconnections xml is invalid due to missing namespace prefix

[Vincentvd-T]

What is the bug or the crash?

From the QGIS browser, you can export the webconnections (e.g. xyz tiles, wm(t)s connection etc) to an xml file. However, this xml file is not valid xml because the http-header prefix is unbound/not defined. The result is that without preprocessing, tools like Python don't accept this xml.

<!DOCTYPE connections>
<qgsXYZTilesConnections version="1.0">
    <xyztiles username="" zmax="18" name="OSMq" password="" tilePixelRatio="0" zmin="0" authcfg="" url="https://tile.openstreetmap.org/{z}/{x}/{y}.png" referer="" http-header:referer=""/>
</qgsXYZTilesConnections>

Steps to reproduce the issue

1. Add https://tile.openstreetmap.org/{z}/{x}/{y}.png as XYZ tileserver connection in the QGIS browser
2. Export the connection as xml
