Enforce type header validation not working in APIM 4.1.0 when using IS 5.11 as KM

[JanakaPushpakumara]

Description

When using apim 4.1.0.170 and is 5.11.0.370 as a KM. whewn we use the below param which was introduced with https://github.com/wso2-enterprise/wso2-apim-internal/issues/6576 in apim gateway deployment.toml.

[apim.token.validation]
enforce_type_header_validation = true

it didn't work because WSO2 IS (as key-manager) still produced access tokens without "typ" header however this type header is available in the token which was generated in IS 6.1.0 and the above param and fix is working for IS KM 6.1.0

The type heander added with the git issue in wso2/product-apim#11703

Thanks,
Janaka.
