feat(instr-tedious): support tedious@18 (#2381)

tedious@18 adds its own .d.ts files. Compiling with them requires
TypeScript v5, and either target:'es2022' for 'AggregateError'
or using skipLibCheck:true in tsconfig.json.

This change limits the update to TypeScript v5 to just while
testing tedious@18 via test-all-versions' support for
'peerDependencies'.

THis also drops ts-mocha in favour of 'mocha --require ts-node/register'
as was done on opentelemetry-js.git in open-telemetry/opentelemetry-js#4840

Closes: #2266
