Beta 0.30 Bug: Dayjs locale cannot be changed

[b-a-b-i-s]

Describe the bug
Dayjs is not externalized in rollup configuration options, and as a result, the dayjs locale used in Timeline cannot be changed.

To Reproduce

Code: https://codesandbox.io/p/devbox/nostalgic-currying-c92smn?workspaceId=ws_5sShTGVVdpwiaXok3xYmZW

Adding the following code before the usage doesn't change Timeline texts to Greek.

import 'dayjs/locale/el'

dayjs.locale('el')

Expected behavior
Months and day of the week names should display using the dayjs locale language.

For example:

Library Version
0.30.0-beta.3
