Improve "Create Lookup Table" action - allow lookup table keys to populate multi fields when the value is comma-separated

Suggestions

• It would be very beneficial to read a CSV file to dynamically import the CSV data to a lookup table. A possible manual way to import data from a CSV to a lookup table in Jira Cloud Automation would also help with this process.
• As a user, I would like to be able to include multiple values separated by a comma in a single key of the lookup table to populate an array field type.

For example:

When creating a lookup table like the following example:
MultiUser

I would like to use smartvalue

{{MultiUser.get("user")}}

And as a result, populate a multi-user picker accordingly with values user@email and user2@email.
