Region descriptions are rendered as JavaDocs. Could we do better?

[alisevych]

Description

Not rendering region description are being generated for Enum tests.

To Reproduce

1. Run the 'lrs' project in IntelliJ Idea
2. Install one of the latest plugin builds from main into IDEA
3. Summaries are on, default type is chosen - with Java docs tags
4. Generate tests for LongRangeType
5. Open the generated test
6. Do the same for Plain text summaries

Expected behavior

Region descriptions can be rendered and links are resolved.

Actual behavior

Region description is formatted with /// and stays as plain text when Java docs are rendered.

Visual proofs (screenshots, logs, images)

Environment

Windows 10 Pro
IntelliJ IDEA 2022.2.3 (Latest)

We need to discuss what's better

    /// Common steps:
    /// 
    /// Tests execute conditions:
    ///      (myBytes == 8): False
    /// invoke:
    ///     LongRangeType#min() once
    /// return from: return diff < min() || diff > max();

or

    ///region SYMBOLIC EXECUTION: SUCCESSFUL EXECUTIONS #1 for method subtractionMayOverflow(long, long)
    /// 
    /// Common steps:
    /// <pre>
    /// Tests execute conditions:
    ///     {@code (myBytes == 8): False}
    /// invoke:
    ///     {@link com.intellij.codeInspection.dataFlow.rangeSet.LongRangeType#min()} once
    /// return from: {@code return diff < min() || diff > max();}
    /// </pre>

After fast research, it became clear that it involves the changing of rendering different CgElements and so on.
And as a result, we should support two cases of rendering in the package of code related to CgElements or move this functionality to summaries. This is why I decided to leave it in the existing state.

@EgorkaKulikov @alisevych @olganaumenko you need to decide
