feat(instrumentation-typeorm): add support for typeorm@1.x

[katoztmy]

Which problem is this PR solving?

Fixes #3545

typeorm@1.0.0 removed EntityManager#findByIds, and the instrumentation tries to wrap it unconditionally, so patching crashes with "Attempt to wrap undefined property findByIds as function". Also supportedVersions is >=0.3.0 <1, so 1.x is not instrumented at all.

Short description of the changes

• Extended the version range to >=0.3.0 <2. I kept the upper bound to avoid claiming support for major versions that are not verified yet, which is also why the existing code was capped at <1.
• Skip wrapping EntityManager methods that don't exist in the loaded version. In 1.x only findByIds is affected.
• I kept the connection getter as-is. In 1.x it is deprecated but still works (it just returns dataSource), and 0.3.x doesn't have dataSource on EntityManager, so connection is the only property that works on both.
• typeorm 1.x dropped the sqlite driver in favor of better-sqlite3, so the test helper now picks whichever driver the installed typeorm supports. The tests themselves are unchanged.
• .tav.yml runs 1.x in a separate job with node: ">=20" (typeorm 1.0 requires Node 20.19+) and better-sqlite3@^12.0.0, same range as typeorm's own peer dependency.

Tested with typeorm 0.3.x and 1.0.0, 13/13 passing on both. TAV run on my fork: https://github.com/katoztmy/opentelemetry-js-contrib/actions/runs/29142553352

I used AI assistance (Claude) for this change. I reviewed and tested everything myself.

Hi @mhennoch @seemk @t2t2 @weyert — just a gentle ping on this PR, it's been about two weeks since it was opened and CI is green (tested against typeorm 0.3.x and 1.0.0). This is my first contribution here, so happy to adjust anything that doesn't fit the repo's conventions. Thanks for taking a look when you get a chance!
