go install dlv@master is broken due to the use of 'replace'

[hyangah]

We observed breakage in dlv installation (microsoft/vscode-dev-containers#1300)
caused by the use of 'replace' directive.

I understand why this replacement is necessary, however, that
is not compatible with go install command. So, this need to
be addressed before the next release.

% go install github.com/go-delve/delve/cmd/dlv@master  
go: downloading github.com/go-delve/delve v1.8.2-0.20220210175055-dee4437bd088
go: github.com/go-delve/delve/cmd/dlv@master (in github.com/go-delve/[email protected]):
	The go.mod file for the module providing named packages contains one or
	more replace directives. It must not contain directives that would cause
	it to be interpreted differently than if it were the main module.

Since replace is not an option, I think the fix is like

1. make github.com/go-delve/liner to be the real fork (i.e. change module name in go.mod to be github.com/go-delve/liner and release it.*
2. replace all references to github.com/peterh/liner with github.com/go-delve/liner
3. remove replace statement in go.mod here and
4. go mod tidy and go mod vendor

• I tried to skip (1) and went to (2), but go mod tidy keeps insisting to put back github.com/peterh/liner
