apns-http2: v2.0.0 is not pulling in the version of okHttp specified in pom.xml

[alenkalac]

HI - Im seeing issues with apns-http2 within the component im working on -
due to security issues we are to upgrade our okHttp to 4.9.2 - checking pom.xml of this project i can see its pulling in

<okhttp.version>4.8.1</okhttp.version>

exploring my dep tree - i see clevertap is bringing in OkHttp3 instead of OkHttp4

due to common-codecs library by the looks of things, it's getting downgraded back to 3.14.9

+--- com.clevertap.apns:apns-http2:2.0.0
|    +--- com.fasterxml.jackson.core:jackson-core:2.7.0 -> 2.11.3
|    +--- com.fasterxml.jackson.core:jackson-databind:2.1.4 -> 2.11.3 (*)
|    +--- commons-codec:commons-codec:1.11 -> 1.15
|    \--- com.squareup.okhttp3:okhttp:4.8.1 -> 3.14.9
|         \--- com.squareup.okio:okio:1.17.2

Enforcing okHttp4 results in connection errors to apns and seems that there might be issues with http2 client where it gets downgraded to http1 for some reason - this however is not the case with OkHttp3 and works as expected.

This is what i'm seeing with okHttp4
