Fix import path for josharian/impl

[FooSoft]

Looks like josharian decided to rename the master branch to main, which unfortunately breaks the vim-go GoInstallBinaries / GoUpdateBinaries commands for that tool.

Updating the import path.

Thank you.

What problem are you actually seeing? I'm still able to install impl with :GoUpdateBinaries impl.

[FooSoft]

@bhcleek I'm not able to pull down impl because the master branch doesn't exist (and nvim complains about this when running :GoUpdateBinaries. I'm not sure why you aren't seeing this too.

Running git version 2.38.1 and go version 1.19.3 The rest of the tools end up getting pulled down without issue. Maybe related to me running NeoVim? Seems unlikely.

Is your GOPROXY (i.e. go env GOPROXY) set to direct instead of https://proxy.golang.org,direct by chance?

[FooSoft]

It is indeed just set to direct, which I believe is the out-of-the-box default on Fedora (where I'm using this).

[bhcleek]

Thank you for confirming. I'll merge very soon.

FWIW, you can unset GOPROXY or explicitly set it to the default value, https://proxy.golang.org,direct, in order to work around this problem, too.
