Redundant update sites not updated

[hohwille]

We had to update two eclipse update-sites here:
https://github.com/devonfw/ide-settings/tree/master/eclipse/plugins

However, if no projects are configured in the settings git there is legacy support via redundant configs here:

ide/scripts/src/main/resources/scripts/command/eclipse

Line 171 in b092a64

doInstallEclipsePlugin "com.devonfw.cobigen.eclipse.feature.feature.group,com.devonfw.cobigen.tempeng-freemarker,com.devonfw.cobigen.htmlplugin,com.devonfw.cobigen.javaplugin,com.devonfw.cobigen.jsonplugin,com.devonfw.cobigen.openapiplugin,com.devonfw.cobigen.propertyplugin,com.devonfw.cobigen.textmerger,com.devonfw.cobigen.tsplugin,com.devonfw.cobigen.tempeng-velocity,com.devonfw.cobigen.xmlplugin" "https://dl.bintray.com/devonfw/cobigen.p2/"

As we can see for CobiGen we still have the old bintray URL that is not working anymore. See #567
Also there was this fix:
devonfw/ide-settings@8dbadc2#diff-8a11a5d42991fc938bd2470234d1f27698f7d114945e2bdd1ac5bee73ea534c2

These changes have to be reflected in the eclipse commandlet as well.
