Remove dependency on deprecated `@sentry/types` package

[antonis]

Problem

The SDK lists @sentry/types as a dependency in packages/core/package.json, but @sentry/types is deprecated and will be removed in the next major version of the JavaScript SDK. All types are now exported from @sentry/core.

No source files in packages/core/src/ actually import from @sentry/types — the dependency appears to be unused.

Solution

• Remove @sentry/types from dependencies in packages/core/package.json
• Remove @sentry/types from the yalc:add:sentry-javascript script
• Verify no transitive consumers rely on @sentry/types being hoisted from this package
