Text edits at the same position are not applied in LSP spec order

[scriptacus]

When multiple text edits have the same position, lsp4ij does not preserve their array order as required by the LSP specification.

LSP Specification:

From the Language Server Protocol specification for CompletionItem.additionalTextEdits:
"If multiple inserts have the same position, the order in the array defines the order in which the inserted strings appear in the resulting text."

Issue:

The TEXT_EDITS_ASCENDING_COMPARATOR in LSPIJUtils.java returns 0 for edits at the same position, resulting in an unstable sort that doesn't preserve the original array order.

lsp4ij version: 0.19.2-SNAPSHOT
