fix: mooring product processing level attribute for level 2

[evacougnon]

@mhidas the file_version and file_version_quality_control description in the hourly timeseries products did not match our documentation

The aggregated product showing Level 1 file version has the same description as shown in the table on page 25, so I assumed Level 2 should also show the corresponding text.

Following this fix we may want to re-process the hourly timeseries

👍 Good catch, and thanks for the fix.
While we're at it, though, the same fix is also needed in the gridded product.
