Embedded Wallets: standardize parameter presentation

[m4sterbunny]

Standardize presentation of parameters across:

• optional vs required items, this is sometimes handled with ? at end of parameter --> Discussed with @yashovardhan

Decision is for ? for optional and then (Required) at the start of the description for the not-optional

• add column to tables to support type

For booleans, this will then allow Default: none | Default: true (or t or 1, per the config) | Default: false (or f or 0, per the config) at the start of the description

• true and false as true and false
