Feature request: Support for TS 5.0

[sevenc-nanashi]

Currently tsserver cannot parse TS5.0 feature, such as const type parameters.

Could you update to support them? Thanks.

By default, coc-tsserver uses the bundled TypeScript. It seems that your issue is arising because the bundled TypeScript is version 4.9. Please try configuring it to use the TypeScript version specific to your project. "tsserver.useLocalTsdk": true or etc...

Resolved with tsserver.chooseVersion, thank you for support.
I keep this Issue open, please close this Issue if it's not needed.

This can be closed as it's already supported.

Thanks.
I felt it seems little confusing. How about making tsserver.useLocalTsdk defaulting to true?

tsserver.useLocalTsdk defaulting to true?

Could break things, my suggestion is use user configuration like:

  "tsserver.tsdk": "/lib/npm/lib/node_modules/typescript/lib",

and update typescript module by npm i -g typescript@latest, so all projects use latest tsserver.
