fix: exclude .env file from init commit #416

[2bitburrito]

Changed gitignore file.close from defer to explicit so as to ensure .gitignore is written before running git commands.

This fixes issue #416.

@2bitburrito Did you check if this approach works?

[2bitburrito]

Yep. I wrote a quick n dirty gh action to show it passes on a window's system.

It was consistently failing before removing the defer so I do believe that it was a filesystem buffer issue.

Apologies if this is at all messy. It's my first pull request for open source.

[2bitburrito]

I just made a change. Rather than losing the .Defer() I added .Sync() which is safer if an error occurs before the file.Close() is executed.

I believe this solves the issue?

You can see outputs from the gh actions test:

All git tracked files:

.air.toml
.gitignore
Makefile
README.md
cmd/api/main.go
go.mod
go.sum
internal/server/routes.go
internal/server/routes_test.go
internal/server/server.go

So the file is present in the directory and not being tracked by git.
