Code Action: Attributes Packing - Context Awareness

[Malix-Labs]

Is your feature request related to a problem? Please describe.

Currently, using the Attributes Packing ("Pack dotted path to nested set") Code Action is not context aware, which provides a suboptimal UX

Example

Using the Attributes Packing ("Pack dotted path to nested set") Code Action on :

{
  a.b.c = true;
}

Will always output :

{
  a = { b.c = true; };
}

No matter where the cursor is

Describe the solution you'd like

Making the Attributes Packing ("Pack dotted path to nested set") Code Action context aware

Example

Using the Attributes Packing ("Pack dotted path to nested set") Code Action on :

{
  a.b.c = true;
}

Should output :

{
  a.b = { c = true; };
}

If the cursor is between b and c included
