Update fitbitjson_mysql stream defaults, relocate pid column, fix typo

[jenniferfedor]

This PR includes a few minor quality of life updates:

• Relocate the participant ID column from the very end to the very beginning of the merged processed sensor feature data file
• Change the default settings for the fitbitjson_mysql data stream to match PittBit's format, which uses fitbit_id as the device ID, data as the JSON Fitbit data column, and the fitbit_data table as the container
• Fix a typo in the Fitbit steps intraday RAPIDS provider sumdurationactivity5to10minutes feature. Note that this issue only affected the name of the feature and not its computation
