add a folding provider

https://github.com/Microsoft/vscode/issues/46200 asks for syntax aware folding for XML.

It would be cool if vscode-xml could implement the foldingRangeProvider API.

Are there options that don't require me to install Java? Why does that plugin require

Java JDK 8 or more recent Ensure Java path is set in either: java.home in VSCode preferences Environment variable JAVA_HOME or JDK_HOME

[angelozerr]

No, you need Java. redhat.vscode-xml consumes the lsp4xml language server which is written in Java. The main reason is that, lsp4xml is using Xerces Java which provides a very good XML Schema support which is used for completion and validation when XML files are linked to XML Schema.

Please note that vscode-xml 0.15.0 from Red Hat no longer require Java, so you will benefit from folding feature.
