feat(router-generator): add a biome-ignore comment on the generated route-tree file

[k35o]

Errors do occur in routeTree.gen.ts in projects that use biome to check code.
I would like to ignore the errors in the generated files as well as in the response to eslint.

@k35o can you please update the test snapshots in packages/router-generator/tests/generator/**/routeTree.expected.ts with the new line being added in.

@SeanCassiere
Thank you! I update it!

[schiller-manuel]

instead of adding each possible ignore instruction separately, I would rather add a possibility to let the user customize the header.

either by supplying a file path that should be used as header or as a string that will be put on top of the generated file

[SeanCassiere]

@schiller-manuel an array of strings would probably make the most sense.

Also, this change would require the ability to both prepend and append to the file in that case, since some tools have their comments set up in a way to pause tracking and resume tracking.

@schiller-manuel PR is up!

#1502

[SeanCassiere]

Superseded by #1502.

@k35o thank you for your contribution which led to a user-customizable feature being added in #1502.

You can upgrade the router-generator to version 1.30.0 and configure the header content of the generated route-tree file using the routeTreeFileHeader field (see documentation here: https://tanstack.com/router/latest/docs/framework/react/guide/file-based-routing#options)
