Multiline containers no longer allow indented folding

[Irmitya]

Environment data

• Language Server version: 2022.1.3
• OS and version: Windows 10
• Python version (& distribution if applicable, e.g. Anaconda): 3.9.6

Expected behaviour

When code/text are enclosed and indented, this would allow the code/text to be folded per indentation

Actual behaviour

Only the initial enclosure is considered and subsequent indentations are completely disregarded

Code Snippet / Additional information

Issue brought from item 4 of a comment in #2248
Example originally used is a dictionary, however the case applies to everything:

items = [
    "Numbers",
        1, 2, 3, 4,
    "Letters",
        "a", "b", "c", "d",
    # Symbols
        "!", "@", "#", "$",
]

Currently, only items can be folded, folding everything to the end bracket.
That should happen, in addition to being able to separately fold Numbers and Letters and (commented) Symbols.

Note: a difference between 2022.1.3 and the one I'm using, 2022.1.0, is when folding items, the end bracket now also collapses.
This is also a problem, because it's not indented, however the main issue is that none of the indentation matters anymore.
