fix(gradle): set init_options.settings.gradleWrapperEnabled #1994

Problem:
gradle-language-server doesn't work well without some kind of
`init_options.settings` parameters. There's some important stuff in:
https://github.com/microsoft/vscode-gradle/blob/a0151761aa2a6a07b64ced0dda5f6e9f01e77fd9/gradle-language-server/src/main/java/com/microsoft/gradle/GradleServices.java#L162-L169
that won't get called unless `init_options.settings` is at least defined. In
particular if `settings == null`, gradleWrapperEnabled will be `null` as well
and
https://github.com/microsoft/vscode-gradle/blob/a0151761aa2a6a07b64ced0dda5f6e9f01e77fd9/gradle-language-server/src/main/java/com/microsoft/gradle/resolver/GradleLibraryResolver.java#L106
`libFolder` won't be resolved.

Solution:
Set `init_options.settings.gradleWrapperEnabled=true` because it's a sensible
default, then `init_options.settings` isn't empty.
