[CHORE]: Embedder embedText length check

What happened?

Continuation of #1238

When embedding a string or array of strings we need to ensure that every item is < the length of the maximum length of the selected embedding model or else the embedder will fail to encode and vectorized a prompt.

This only applies to the prompt given, which tends to be below the embedders length, but we need to ensure this is always the case via a util/helper function.

Are there known steps to reproduce?
