[JosephVolosin]

This pull-request updates the 'Send to Workspace' feature in plan expansion to let the user create a new file in a sequencing workspace loaded with the expansion result of an expanded sequence.

Testing

1. Set PUBLIC_COMMAND_EXPANSION_MODE=templating in .env to enable Sequence Templating expansion
2. Upload bananation.jar
3. Upload command_dictionary.xml, and create a new parcel called Test with it
4. Create a Workspace using the Test parcel
5. From the Sequence Templates menu option, create a new Sequence Template with the following criteria:

Template Name: Test
Template Language: Text
Parcel: Test
Model: Bananation
Activity Type: BakeBananaBread

6. Modify the content of the Sequence Template to say Test data
7. Create a new plan with the Bananation model, any time range
8. Insert a BakeBananaBread activity, set arguments to any values, simulate
9. Under Expansion, create a new sequence called Test
10. Add the BakeBananaBread activity to the Test sequence
11. Within the Expansion panel, hover over the Test sequence and click the play/Expand Sequence button
12. Within the Expansion panel, hover over the Test sequence and click the Send Expanded Sequence to Workspace button
13. Select the previously created workspace and click Save
14. Enter Test.txt for the filename and click Confirm
15. Navigate to the workspace and confirm the file is created with the Test data content inside

Do you also mind adding permission checks to the workspace dropdown or submit button for if the user even has access to the workspace that they want to send the sequence to? There is a featurePermission.workspace() in utilities/permissions.ts that you can use to see if the user can upload to the selected workspace.

Added a one-line fix in 1767257 since the function signature for getWorkspaceContents changed in another merged PR. Ready to merge when tests pass!
