Fix the redirection to "files" when exporting in observed data and notes

[CelineSebe]

Proposed changes

• Add the 'redirectToContent' props to the roots of notes and observed data

Reproducible Steps

In Events/observed data and Events/Notes:

1. Click on the quick button export, at the top right
2. Verify that the page displays correctly with 'files?' in the URL and not 'content?'

Actual Output
