Preserve generateUUID call signature compatibility

generateUUID is re-exported as part of @datadog/browser-core (packages/core/src/index.ts:156), but this change narrows its TypeScript signature from generateUUID(placeholder?: string) to zero arguments only. That is a source-compatible break for any typed consumer currently passing an argument (including undefined), which will now fail with “Expected 0 arguments” even though runtime behavior still accepts extra args. For a bugfix commit, this API break is unexpected and should be avoided by keeping the previous optional parameter in the signature.
