[FEATURE] Add dependency to dataSourceManagement bundle

[derek-ho]

Is your feature request related to a problem?
Acceptance criteria: in the opensearch_dashboards.json file, add dataSource as required bundle, eg. "requiredBundles": ["dataSourceManagement"]

What solution would you like?
Adding a dependency to the dataSourceManagement bundle and plugin tests/builds pass with and without multiple datasources enabled.

What alternatives have you considered?
None

Do you have any additional context?
This is a pre-requisite to consuming the shared/common DataSource Picker component that is shared among plugins/core.
More context can be found here:
