v0.8.0 bug fixes and doc string fixes

[akeeste]

This PR addresses several bug and doc string fixes in v0.8.0. I think it's critical that we make these fixes before our workshop next Thursday.

I tested all of our Python examples on a clean install of MHKiT with Python 3.11. There are several examples with errors

• [ ] ADCP_Delft3D_TRTS_example.ipynb - Scipy interpolation error
• [ ] cdip_example.ipynb - Error indexing by YYYY-MM. Passes in 3.9 but not 3.11
• [ ] directional_waves.ipynb - Error reading cached data. Passes in 3.9 but not 3.11
• [ ] metocean_example.ipynb - Pandas date indexing error. Passes in 3.9 but not 3.11
• [ ] PacWave_resource_characterization_example.ipynb - Folium map error
• [x] qc_example.ipynb - mhkit.utils.index_to_datetime is removed/renamed
• [x] tidal_example.ipynb - Error slicing by time. Passes in 3.9 but not 3.11
• [x] wave_example.ipynb - Warning about pd.csv_read infering a date format. Error defining the "mean" statistic
• [x] WPTO_hindcast_example.ipynb - error getting the variable significant_wave_height_0

Incorporates several minor documentation fixes:

• [x] updates links in NOAA functions
• [x] fixes formatting in the mooring example
• [ ] mitigate warnings due to doc string issues, spacing, etc
