Regression in non-inline HyperText/iframe HTML support caused by a fix to a hypothetical vulnerability

[dchichkov]

Describe the bug
Annotating data within an iframe (wikipedia articles, etc) in the HyperText element is no longer possible, as <script> tags are filtered out from HTML content starting from 1.11.0. This is a regression in 1.11.0 caused by #5232

To Reproduce
Use non-inline iframe in the HyperText element and include <script> tag.

Expected behavior
It should be possible to render modern HTML that includes scripting withing the HyperText/iframe.

Environment (please complete the following information):

• OS: [e.g. iOS]
• Label Studio Version 1.12.0

Additional context
Sanitized internal data or data from sources like wikipedia can not contain a hypothetical vulnerability highlighted by this CVE. This hypothetical vulnerability is also unimpactful, as the service is stand-alone and isolated from any high-value financial/industry targets.
