Improve Internship summary description

[philipmjohnson]

Please do work for this task in a branch called issue-807.

You can see the full list of Internship summaries by going to: https://radgrad2.ics.hawaii.edu/#/admin/radgrad@hawaii.edu/explorer/internships

These summaries can be improved by updating the default implementation of process-listings (https://internaloha.github.io/docs/developers/process-listings ) to strip descriptions that begin with:

• "The position"
• "What you'll do"
• "Who are we?"
• "About the role:"
• "Why join us"
• "Who we are" or "Who we are."
• "We are looking for"
• "The basics"
• "Company overview"
• "Position"
• "About us"
• "About the job"
• "Role & Responsibilities:"
• "DESCRIPTION:" or "Description:"
• "Job Summary:"
• "Your responsibilities include: "
• "Introduction"
• "Research Topics/Keywords: "
• "Full Job Description"
• "What You’ll Do"
• "Overview"
• "Company Description"

As a second pass, strip any leading newlines.

Also note that the Apple scraper does not appear to set the Company field. Those listings get an "undefined" in the title.

Made updates to processListings to hopefully implement the above. There may be additional strings to remove so I am keeping this issue open for now.
