build: ship docs/oauth-scopes.md in the npm package

OAuth scopes are enforced server-side and appear nowhere in the shipped
types — code with missing scopes compiles cleanly and 403s at runtime.
Shipping the per-method scope table with the package gives developers,
IDEs, and coding agents a version-exact scope reference at
node_modules/@uipath/uipath-typescript/docs/oauth-scopes.md, next to
the .d.ts they already read. Verified via npm pack --dry-run (+10.2kB).
