fix: restore typescript 5.6 compatibility

[blimmer]

This PR restores compatibility with TypeScript 5.6. It also updates the test suite to be more resilient and explicitly tests against TypeScript 5.5 and 5.6.

I was surprised that TypeScript would break this without releasing a major version. However, if you look at the getOriginalSourceFile method we were using, it was marked as @internal in the JSDoc: https://github.com/microsoft/TypeScript/blob/c8a7d589e647e19c94150d9892909f3aa93e48eb/src/compiler/utilities.ts#L5416-L5419

Because it was marked as internal, they probably reserved the right to remove this method without a breaking version bump. The other PR to fix this issue (#270) suggested using getSourceFileOfNode, but that's also marked as @internal: https://github.com/microsoft/TypeScript/blob/11b2930fa2c9f73b0ffb725a9715b8d3c4121bbc/src/compiler/utilities.ts#L965-L975.

Therefore, instead, I updated this code to use getParseTreeNode and isSourceFile, which are both exposed publicly and not marked as internal: https://github.com/microsoft/TypeScript/blob/11b2930fa2c9f73b0ffb725a9715b8d3c4121bbc/src/compiler/utilitiesPublic.ts#L803-L809 / https://github.com/microsoft/TypeScript/blob/11b2930fa2c9f73b0ffb725a9715b8d3c4121bbc/src/compiler/factory/nodeTests.ts#L1013-L1016

By using these methods, we should be more resilient to internal refactoring.

This PR supersedes #270.
Fixes #266

See PR description - both of these methods are not marked as @internal.

This is the exact implementation of getOriginalSourceFile: https://github.com/microsoft/TypeScript/blob/c8a7d589e647e19c94150d9892909f3aa93e48eb/src/compiler/utilities.ts#L5416-L5419

Technically, 5.6.3 and latest are the same thing right now. However, I wanted to explicitly define 5.6.3 so we run tests against it. Then, when 5.7++ come out, we'll get test coverage.

These tests were failing for me when I ran them locally. The output of yarn seems to include control characters to bold the string null, which is why I'm stripping the string with this method.

Also, instead of caring about the newline (which can be different between windows and mac), I just .trim() it.

Thank you for the contribution @blimmer. Overall LGTM. I'll take some time this week to try this out, give it a proper review&test and see if we can get it merge.
