Adjusts minimum Go version in documentation to 1.11

[saitho]

Gitea uses the "-mod" option in go run which is introduced with Go v1.11.
Documentation states 1.9 as minimum version. Therefore we should update documentations. :)

[techknowlogick]

Minimum go version supported is 1.10, as we need to ensure that go build works for that version. This will change when Gitea v1.9.0 is released when we can move to go 1.11

I would be fine merging this with the release of 1.9.
Just checked out master and noticed that I need Go v1.11 in order to compile it.

As we will be releasing Gitea 1.9 soon, there is a freeze and as such a change such as this will have to wait until after 1.9 is released.

You shouldn't, and in fact each commit to master is checked that it can compile with Go v1.10

Hm. Building with Go 1.10 fails saying that the option -mod is not available for "go run", pointing to this file: https://github.com/go-gitea/gitea/blob/master/modules/options/options.go on line 7.
Might also be a misconfiguration on my end, as I installed Go on a freshly installed Ubuntu. ^^

[techknowlogick]

For reference here is the command you can run: https://github.com/go-gitea/gitea/blob/master/.drone.yml#L65 the makefile may not support 1.10, but running with just go build does

Fail happens when you build with bindata using makefile (TAGS="bindata" make generate). I think this should be remarked

[sapk]

It is only the makefile that break compat for The build command. We can maybe introduce build-compat command. We check compat with 1.10 on the CI. The command make release or make release-linux (or the os of your choice) should still work.

[sapk]

Looking at #7149 the command make generate is maybe also broken by the need of Go1.11

[lunny]

Maybe because I introduced the vfsgen and add -mod=vendor on go generate.

[lunny]

I think we can fix this by remove -mod=vendor in go generate on release v1.9 and added it back on v1.10 :)

[techknowlogick]

This has been accomplished in another PR. Thanks for PR :)
