troubleshoot test pipeline, recently failing

[iambumblehead]

this PR started off as routine incrementing of a ci "action" but turned into something else when the pipelines failed for a separate reason. For reasons discovered later, tests/tests-jest-ts/tsconfig.json needed this change

{
- "extends": "ts-node/node16/tsconfig.json",
+ "extends": "./node_modules/@tsconfig/node16/tsconfig.json",
  "ts-node": {
    "transpileOnly": true
  },
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "module": "ESNext",
    "moduleResolution": "node"
  }
}

$ node --version
v21.2.0

tests do not fail here...

these seem related nodejs/node#48207, LibreService/my_rime#23

[...] switch to Node.js 18 just to see the actual error.

In the node 18 environment, the error looks like this

I did try troubleshooting this error a little bit but the solutions I tried failed and I was not sure the error was the original source of the problem. I could try re-enabling the jest ts test and making changes there, but it would be a trial and error thing and I don't know if the issue can be resolved or how many "trials" it would take to find a solution

tests pass when tests-jest-ts are disabled... the error does not occur with other test folders where node-ts is used

    "test:DISABLEnode18-test-jest-ts": "cd tests-jest-ts && npm test",

this change seems safe to merge now, so merging
