fix: clipboard package not working with CGO_ENABLED=0 [ROAD-1185]

[j-luong]

Description

This PR replaces the clipboard package due to compatibility issues when building with CGO_ENABLED=0. Before merging we will need to verify that the changes work on all platforms.

Validation procedure

• Use goreleaser to build LS binaries in golang docker container:

docker run --rm -it -v ${PWD}:/app -w /app golang
go install github.com/goreleaser/goreleaser@latest
goreleaser build --rm-dist --snapshot

• Wire built binary as custom LS path in VSCode
• Open extension and try authenticating from scratch
• Press “Copy authentication link to clipboard”
• Auth link should be copied to clipboard (paste to verfiy)

Checklist

• Tests added and all succeed
• Linted
• Validated on darwin_arm64
• Validated on darwin_amd64
• Validated on linux_386
• Validated on linux_amd64
• Validated on linux_arm64 (with xsel installed)
• Validated on windows_386
• Validated on windows_amd64
• License file updated, if new 3rd-party dependency is introduced

There's a package requirement to have xsel or xclip for Linux, if these are missing, testing on linux_arm64, copyAuthLink fails with: Snyk encountered an error: No clipboard utilities available. Please install xsel, xclip, wl-clipboard or Termux:API add-on for termux-clipboard-get/set.

Would you please the documentation to

• readme
• gitbook

Also, please create a followup story to

• display the needed dependency on vscode linux
• add to vscode documentation

[j-luong]

@bastiandoetsch as we're going down the 2 packages option, would the doc updates still be required? Linux shouldn't have a dependency requirement with golang.design/x/clipboard.

There's actually a dependency on CGO_ENABLED=1 for Linux in the golang.design/x/clipboard package. This means that we can't use 2 different packages.

Will revert back to having a requirement for Linux and update the docs as suggested

[j-luong]

Docs (README, GitBook/VSCode) have been updated.
