Closes#47086
This PR detects completion items ending with `=` (which typically
represent keyword arguments in function calls provided by
`Pyright`/`BasedPyright`/`pylsp`) and assigns them the highest sorting
priority.
This ensures that when a user is filling out function arguments, the
named parameters appear at the top of the list, rather than being buried
mixed with other symbols.
After fix:

/>
> **Note on Sorting:** Currently, these named arguments will be sorted
alphabetically by label. Preserving the original order of the function
definition would be ideal, but it requires information not currently
available in this logical block. Insights on how to retrieve the
definition order would be appreciated.
> **Note on other LSPs:**
> * **`ty`**: Already provides well-sorted completions natively, so no
intervention is required.
Release Notes:
- Improved completion order for Python-based LSPs
