Updated vscode-json-languageservice to 5.3.9

[harrismirza]

Updated vscode-json-languageservice to the latest version, in order to fix the bug where validating JSON against the latest JSON Schema Drafts would not work correctly (microsoft/vscode-json-languageservice#122)

[harrismirza]

@microsoft-github-policy-service agree

[harrismirza]

Just to add, this would also resolve issues #3625, #4114 and #3160

@hediet @aeschli Would you be able to review this?

Wondering if this will be included in the March release, am heavily invested in seeing support for 2020-12 schema support. Am willing to help out in any way I can.

[aeschli]

@daviesgeek full 2020-12 schema support is still not implemented in vscode-json-languageservice. There's currently no resources to work on this on our side.

[harrismirza]

Hey @aeschli, @deepak1556,

Is there a reason this wasn't included with the March release? I was looking forward to using this.

Even though this doesn't include full schema 2020-12 support, currently just having the schema property set to anything newer than draft-07 completely breaks validation.

[harrismirza]

Hey, sorry to keep asking about this, but is there a particular reason this merge keeps being pushed?

[jrsquared]

Same question. I've been telling customers that it is coming, first in March, then April, and now May.

[daviesgeek]

Same here

[hediet]

Thanks for the PR and sorry for the delay! Just updated all of the langugae services.

Thank you!
