Adding a note for increasing the size allocated for CALLBACK_URL for DCR flow.

Description: For DCR flow there can be situations where TPP can be using a callback_url which exceeds the default sizes allocated for the column CALLBACK_URL in AM_APPLICATION (varchar 512) table & IDN_OAUTH_CONSUMER_APPS (varchar 1024) table.

According to the response we got from OBIE for the query in [1], there is no limit on the number of redirects you can add and according to UK open banking specification [2], each URL can contain up to 256 characters.

Therefore it's better to add a note in [3] & [4] before the section Registering an application to increase the column size of the column CALLBACK_URL in their database environment accordingly to cater to such situations.
