Add `.next` and `.turbo` to defaultExclude

[domdomegg]

Clear and concise description of the problem

As a developer using Vitest I want common build outputs created excluded so that duplicate versions of tests don't run, and it's easier to get set up without having to provide more config.

Currently the defaultExclude has rules for karma, rollup, webpack, vite, vitest, jest, ava, babel, nyc, cypress, tsup, eslint and prettier.

I would argue that both next and turbo are projects with higher usage levels than some in this list, and therefore it's reasonable to include them.

Suggested solution

+export const defaultExclude = ['**/node_modules/**', '**/dist/**', '**/cypress/**', '**/.{idea,git,cache,output,temp,next,turbo}/**', '**/{karma,rollup,webpack,vite,vitest,jest,ava,babel,nyc,cypress,tsup,build,eslint,prettier}.config.*']
-export const defaultExclude = ['**/node_modules/**', '**/dist/**', '**/cypress/**', '**/.{idea,git,cache,output,temp}/**', '**/{karma,rollup,webpack,vite,vitest,jest,ava,babel,nyc,cypress,tsup,build,eslint,prettier}.config.*']

Alternative

Tell users to manually exclude these files.

Additional context

I'm happy to submit a PR for this.

We are actually planning to reduce the number of default entries in defaultExclude: #6287

Do both .next and .turbo duplicate test files? I think it's reasonable to include them if so, but also maybe it's a good idea to encourage people to configure their setup to not bundle tests since they won't be used by anyone?

I would recommend using the test.dir option to limit the folder where tests are located.

Yeah, at certain stages during the caching / bundling process they copy these over. I think the bundled output itself doesn't include test files, but these directories still do.

I'd also be fine with removing all the other entires from defaultExclude, and then making it very obvious in the docs how to exclude certain files. It's just weird that it's only for half the tools I commonly use.

We decided to keep the exclude to the minimum like we wanted previously in #6287. It only excludes node_modules and .git folders by default.
