Body templating not working when `Content-Type: application/json` not present

[CodeShellDev]

Description

Even when using Query-to-Body injection the body cannot be read again (resulting in Data: null),
because GetReqBody() expects Content-Type to be set to json or form.

To Reproduce

Steps to reproduce the behavior:

1. Start Container
2. Send Request with @test=no (or sth. else)
3. Use Field Policy, etc.
4. See that body doesn't seem to have updated

Expected behavior

Automatically write content type header into request after Write().

Container logs

secured-signal  | {
secured-signal  |   "Data": null,
secured-signal  |   "Raw": "eyJ0ZXN0Ijoibm8ifQ==",
secured-signal  |   "Empty": true
secured-signal  | }

Notice Empty: true even tho Raw isn't,
also, the raw output is only base64 encoded because of the logger, but actually raw holds the real json data.
So Data shouldnt be null.

Config files

    fieldPolicies:
      "@test": { value: no, action: block }

Additional Context

This bug is due to gotl, not writing the content type header after a sucessful write.
And has been fixed in v0.0.11 (or v0.0.12).

[CodeShellDev]

Will be released in a bugfix: v1.4.4
