go generate ./... no longer works with go 1.22.0 and wire 0.6.0

[scr-oath]

Describe the bug

wire ./... seems to work fine, but go generate ./... now fails due to the use of go run with -mod=mod

go version
go version go1.22.0 darwin/arm64

grep wire go.mod 
        github.com/google/wire v0.6.0

To Reproduce

Create a wired module and try to run generate to re-wire it.

go generate ./...
# ...
go: -mod may only be set to readonly or vendor when in workspace mode, but it is set to "mod"
        Remove the -mod flag to use the default readonly value, 
        or set GOWORK=off to disable workspace mode.

Expected behavior

go generate should work just as well as wire - the generated //go:generate line should not be so different that it cannot run.

Version

0.6.0

Have the same issue for
go version go1.21.6 darwin/arm64 and the latest wire v0.6.0
My project uses go workspaces (there is go.work file in the root). This is the main reason for the issue, probably.

It is fixable by removing "-mod=mod" from the generated wire_gen.go file. But it returns after the next code generation.

Here is the problematic line: https://github.com/google/wire/blame/e57deea2f8bbe2386b756f2555e02de33e20a3f0/internal/wire/wire.go#L270
PR: #353

It makes wire not fully compatible with go workspaces

[alexus1024]

One solution that would work for me:
When the wire gen -header_file flag is specified, do not output the first 3 lines in a generated file ("DO NOT EDIT" comment, new line, go-generate command).

I meet the same problem. In my case -mod=mod can not work in go workspace.
