improvement(core): don't respect .gitignore files by default

The previous default behavior has been known to cause confusion, and
sometimes makes it difficult to correctly control which files should
be used for build contexts. We now default to only respect
`.gardenignore` files.

You can override the default behavior by explicitly setting the
`dotIgnoreFiles` field in your project configuration.

The `garden create project` command now also copies a .gitignore file
next to the project config file, if one is found, and instructs the
user accordingly.

I also added a bunch of .gardenignore files (and sometimes missing
.gitignore files) to our examples.

BREAKING CHANGE:

Garden no longer respects `.gitignore` files by default now. If you'd
like to retain the previous default behavior, you can explicitly set
`dotIgnoreFiles: [.gitignore, .gardenignore]` in your project configs.
If you already have `dotIgnoreFiles` set in your config, no change is
necessary.
