[Doc]: paths map value points to removed baseUrl value

[tanepiper]

Description

The inline documentation for a paths map value says "Path mapping to be computed relative to baseUrl option" however baseUrl has been removed, screenshot included

Option 'baseUrl' has been removed. Please remove it from your configuration.
  Use '"paths": {"*": ["./*"]}' instead.ts(5102)

These tooltips come from schemastore:

• https://github.com/SchemaStore/schemastore/blob/c76669f78bb07ee3214fa36ee2fd56ada99a1418/src/schemas/json/jsconfig.json#L745
• https://github.com/SchemaStore/schemastore/blob/c76669f78bb07ee3214fa36ee2fd56ada99a1418/src/schemas/json/tsconfig.json#L749

They'll need to be updated at some point; we could send a PR there now if we can come up with some neutral language that works for all versions of TS.
