x/tools/gopls: provide links for replace in go.mod

gopls version

gopls tip

go env

What did you do?

1. in local replacement case, the local path doesn't have a link.

2. in case of require A v1.2.3, replace A => A v2.3.4, if I click the required module, it jumps to v1.2.3 go doc rather than v2.3.4.

What did you see happen?

NA

What did you expect to see?

I would like to support the 2 cases above:

1. the local replacement(replace A => /local/path should have a link to /local/path/go.mod, so once I click the link i can jump to the corresponding module. Adding a go.mod rather than /local/path because vscode will show an empty page if you want to open a folder.
   I want this feature because I define a CLI which helps to insert many local replacements via code generation, and it will be great if the local path has a link so i can click it in vscode.

2. the docs should respect the replace, the jumped link should have version v0.32.0 rather than v0.30.0.

I can help to do the code change, actually I already have a draft here.
