Installation of v.0.40.0 fails with `go install`

[cdillond]

Describe the bug
Installation of lazygit v0.40.0 using go install fails due to a replace directive in the go.mod file.

To Reproduce
Steps to reproduce the behavior:

1. Run go install github.com/jesseduffield/lazygit@latest
2. When I do this, the following message appears:

go: github.com/jesseduffield/lazygit@latest (in github.com/jesseduffield/lazygit@v0.40.0):
	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.

Expected behavior
I expected lazygit to install successfully.

Version info:
I was able to avoid the issue by running go install github.com/jesseduffield/lazygit@v0.39.4 instead.

Additional context
Per the Go docs (and this other github issue), go install doesn't work with replace directives.

I think this might be the source of the problem.
replace github.com/gdamore/tcell/v2 v2.6.0 => github.com/stefanhaller/tcell/v2 v2.6.16

This is being discussed in golang/go#44840, it's a problem in golang's module system that people seem to disagree about whether or how it should be solved.

For the time being, the solution seems to be to not use a replace directive for tcell, but import the fork for real. Starting work on this in jesseduffield/gocui#37.

While this should be solved by #2888, it will of course still not work until we make a new release.
