Mistake in documentation

[pescepalla]

1. The documentation contains the following snippets:

[theme]
name = "native"

[theme]
name = "slick"

However, this does not work and results in an error message

"Failed to deserialize TOML file /home/me/.config/i3status-rust/config.toml at line 1: unknown field name, expected themeoroverrides"

Please replace name with theme.

2. Colors as expressed in the documentation result in i3bar-river failing to deserialize the config. They have to be expressed as #00000000
