Fix ESLint proxy filename typo (eslipnt → eslint)

[Copilot]

After the ESLint 3.0.24 upgrade was merged to master, the proxy JavaScript file was committed with a typo in its filename (eslipnt-lsp-proxy.js), while ESLintLanguageServer.java references it as eslint-lsp-proxy.js. This PR renames the file to match the Java reference, fixing a runtime failure.

• eslint-lsp-proxy.js: Renamed from eslipnt-lsp-proxy.js to eslint-lsp-proxy.js to match the resource reference in ESLintLanguageServer.java

Updated all references to 3.0.24 (git tag, VSIX URL, and tgz — which now all match since the server's package.json at that tag also uses version 3.0.24) in commit d5791f9.

@copilot investigate test failures

All 4 TestESLint tests fail because vscode-eslint 3.x switched from diagnostic push (textDocument/publishDiagnostics) to pull (textDocument/diagnostic + workspace/diagnostic/refresh). LSP4E expects push, so no diagnostics arrive.

Fix in commit 123a25e:

• Created eslint-lsp-proxy.js (following the md-lsp-proxy.js pattern) that intercepts the server's pull model and converts to push — removes diagnosticProvider from capabilities, pulls diagnostics after didOpen/didChange, and handles workspace/diagnostic/refresh from the server.
• Updated ESLintLanguageServer.java to launch through the proxy.
• Overrode refreshDiagnostics() in ESLintClientImpl to acknowledge refresh requests.
• Fixed problems config to provide shortenToSingleLine: false instead of an empty map.

@copilot rebase on master

Merged master into the branch in commit ec3b57a. All ESLint 3.0.24 changes were already in master (commit 26b837f). The only remaining diff is fixing the proxy filename typo (eslipnt-lsp-proxy.js → eslint-lsp-proxy.js) to match the reference in ESLintLanguageServer.java.
