Use toml format for examples in the readme

[bumpver] current_version = "1.5.2" version_pattern = "MAJOR.MINOR.PATCH"

[bumpver:file_patterns] setup.py version="{version}",$ src/mymodule/init.py ^version = "{version}"$

Yeah old syntax, this is a very bad experience if even the first example didn't work.

I'd be fine with switch the examples to use toml format and make the format explicit to avoid future confusion. Would you like to open a PR and make this contribution?
