Inconsistent behaviour in SAML NameID format value

[DilshaniSH]

Describe the issue:
NameID format value is displayed correctly in the management console containing ":" characters. However when we get the SAML inbound protocol information of a service provider, using application management API, ":" characters in the NameID format value is replaced with "/" characters.

How to reproduce:

1. Create a SAML service provider through management console and configure NameID format value as "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress".
2. Retrieve the SAML inbound information of the particular application using application management API.

      Request : 
      curl --location --request GET 'https://localhost:9443/t/carbon.super/api/server/v1/applications/5b90f38e-6bc3-4f83-a5cc-9c6b75ed99da/inbound-protocols/saml' \
      --header 'Authorization: Basic YWRtaW46YWRtaW4='
      

      Response:
      {
          ...................
              "assertion": {
                  "nameIdFormat": **"urn/oasis/names/tc/SAML/1.1/nameid-format/emailAddress"**,
                  "audiences": [],
                  
              }
          }
          .......................................
      }

3. NameID format value is returned as "urn/oasis/names/tc/SAML/1.1/nameid-format/emailAddress".
4. View the NameID format value through the management console and it's displayed as "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"

Expected behavior:
API response to include the nameID format value in the correct format.
