Hover documentation for typescript uses jsdoc rules and not tsdoc

Steps to Reproduce:

1. Write some typescript code and use the syntax required by tsdoc
2. Observe that hover documentation and highlighting completely ignore tsdoc and instead assume parity with jsdoc
3. Cry in pain as you realize that despite being written in typescript, VSCode has shoddy typescript support

Examples:

Thinking that the [mandatory hyphen](https://tsdoc.org/pages/tags/param/) after a parameter name is a markdown hint for a bullet point

Not recognizing the `@defaultValue` tag, and assuming `@default` and `@defaultvalue`


Not understanding [`@remarks`](https://tsdoc.org/pages/tags/remarks/), which is marked as [core](https://tsdoc.org/pages/spec/standardization_groups/), meaning you are expected to recognize it

Not providing hover for `@typeParam`
 

(The list goes on...)

Also, this last remark isn't a bug, but it would be really, _really_ great if you would support [`@inheritDoc`](https://tsdoc.org/pages/tags/inheritdoc/) for hover.

Start by reproducing the listed TSDoc examples in VS Code 1.99.3, comparing hover text and highlighting with the linked TSDoc rules. Trace the TypeScript hover documentation path that handles JSDoc tags, then verify that core tags such as @param, @defaultValue, @remarks, and @typeParam are recognized with the expected formatting.
