[Documentation]: Update Time Intervals Usage in Tutorials

[lawrence-mbf]

What would you like changed or added to the documentation and why?

Due to upcoming changes to the schema in 2.5.0: https://github.com/NeurodataWithoutBorders/nwb-schema/pull/486

Tutorials that use the TimeIntervals class need to be updated to support using TimeSeriesReferenceVectorData
