Rollup merge of #109031 - thomcc:config-example-toml, r=ozkanonur

Rename `config.toml.example` to `config.example.toml`

This had bothered me for a while as it leads to bad (missing) syntax highlighting in most editors I've used, and `@jyn514` suggested I just make the change and that the compatibility concerns I had don't really matter.

I suspect it will be a contentious one, so will not be offended if the outcome of this is to close the PR.
