Does not run on arch: SyntaxError

**Describe the bug**
Does not run on Archlinux when installed from AUR. This used to work fine but sometime in the last few months, I get a syntax error when trying to run the binary.

**To Reproduce**
Steps to reproduce the behavior:
1. Install `diagnostic-languageserver` from AUR
2. Run `diagnostic-languageserver`

**Expected behavior**
Binary runs

**Desktop:**
diagnostic-languageserver version: 1.14.2-1 (According to the AUR)
node version: v12.22.12
linux kernel: 5.18.15
distro: arch

Log:
```
/usr/lib/node_modules/diagnostic-languageserver/node_modules/vscode-jsonrpc/lib/common/linkedMap.js:40
return this._head?.value;
^

SyntaxError: Unexpected token '.'

Reproduce the failure by installing diagnostic-languageserver 1.14.2-1 from AUR and running the diagnostic-languageserver entry point with Node v12. Inspect node_modules/vscode-jsonrpc/lib/common/linkedMap.js, especially the optional-chaining syntax shown in the log. Done means the binary starts successfully on Arch Linux with the reported environment.
