fix: after slicing name trim to remove whitespace

[coreyar]

Original	Updated	Change	Reasoning
scripts/pull_from_dune.py	n/a	strip white space after slicing name	prevents extra underscore between query name and query id

Provide any other context or screenshots that explain or justify the changes above:

If the sliced name ends in white space replacing whitespace with underscores will add an extra underscore at the end of the file which can cause issues when prasing for the query id

Note to Contributor:

Make sure your PR edits the original query_id.sql file with the new query text. If you are proposing adding a new query completely, make sure to add it to queries.yml and as a file in /queries as well.
