Custom asset domain should replace the domain of links in RTE that link to assets

[Webcoda]

Brief bug description

Passing assetsDomain parameter to the DeliveryClient constructor only replaces the asset domain for assets themselves. However, the links that link to the assets still have kontent-ai original asset domain e.g. https://assets-au-01.kc-usercontent.com or https://preview-assets-au-01.kc-usercontent.com.

What went wrong?

Repro steps

1. Need to have configured custom domain
2. Go to any RTE fields
3. Add link to assets
4. See the returned example
   

Expected behavior

The custom domain should be used instead of original assets domain

Test environment

• Platform/OS: Windows 11
• Browser: Chrome
• Version 104.0.5112.81
