fix: add shim for js

[paralin]

Fixes build with:

env GOOS=js GOARCH=wasm go build -trimpath .

[AkihiroSuda]

How is this expected to be used?

[paralin]

It's a shim so that programs built using the console package can compile against GOOS=js as well.

@paralin can you add a little bit more context to this issue. We don't currently have any ongoing efforts to support GOOS=js or issues tracking it. Knowing more about the use case would be helpful.

[paralin]

@dmcgowan The bubbletea TUI packages import containerd/console. I recently submitted several PRs to projects adding shims so that the build will complete if GOOS=js and GOARCH=wasm with reasonable defaults.

I think it makes sense in general to make the package at least build cleanly with that GOOS. Even if the functions are all shims.

[dmcgowan]

@paralin if this library is being used for a platform other than what is explicitly supported, our normal pattern is to include a console_other.go file which builds with ! statements of the supported platforms. The current change in console_js.go aren't specific to any platform.

[paralin]

@dmcgowan okay, applied the change.

[AkihiroSuda]

Please gofmt with Go 1.17

@AkihiroSuda If I do that, the license checker will fail. I previously sent the PR with it formatted that way, and the test failed. The containerd license checker expects this format and doesn't allow the other one.

I updated the linters and licence-checker in #61, and formatted with go1.17

@thaJeztah @AkihiroSuda Fixed & rebased, apologies for the delay!
