removed -s flag from documentation (#2379)

Website documentation fixes:

1. -s does not exist for options, must use --source

2. per data_sources_default.json, fixed incorrect references to sources in options module:
-'tr'  must be full name: 'tradier'
-'ce must be full name: 'chartexchange'

Functions and --help information are already correct, we just needed to correct the website docs

 <h3>Market Coverage and Data Sources</h3>
 
 At the time of writing, OpenBB is able to provide coverage only for US-listed equity and ETF options. While not officially supported, some additional markets and index options may be accessible with yFinance as the source. Coverage will be added as the product grows to incorporate more community contributions but, for now, it is safe to generalize equity options as referring to US-listed companies on a major exchange and are priced in $USD.<br></br>
