Provide support for Jakarta EE

[sleepo581]

Describe the bug

I'm migrating an application from old javax to new jakarta EE packages, however I got a few issues with Uploadcare Java client.
I suppose that Uploadcare uses javax.activation which is conflicting with jakarta.activation package.

The error can be reproduced like this:

• Add com.uploadcare:uploadcare:3.5.1 dependency
• Add jakarta.activation:jakarta.activation-api:2.1.1 dependency
• Try to upload file via FileUploader

Expected behavior

File is uploaded without exceptions

Code / screenshots

java.lang.IllegalAccessError: failed to access class com.sun.activation.registries.LogSupport from class javax.activation.MimetypesFileTypeMap (com.sun.activation.registries.LogSupport and javax.activation.MimetypesFileTypeMap are in unnamed module of loader 'app')
	at javax.activation.MimetypesFileTypeMap.<init>(MimetypesFileTypeMap.java:130)
	at com.uploadcare.api.RequestHelper.getMimeType(RequestHelper.java:80)
	at com.uploadcare.upload.FileUploader.upload(FileUploader.java:127)

Environment

• 3.5.1
