Solarized themes are missing from 0.15.3

[adamtabrams]

What version of bat are you using?
bat 0.15.3

Describe the bug you encountered:
bat --list-themes does show any Solarized themes.
And using bat with a Solarized theme set in the bat.conf gives this error:
[bat warning]: Unknown theme 'Solarized (dark)', using default.

Describe what you expected to happen?
I expected to see both light and dark variants of the Solarized theme using bat --list-themes.
And I expected my bat.conf that uses the Solarized (dark) theme to continue working.

How did you install bat?
homebrew

This is also true for when I installed bat using cargo.

Fixed in #1029. I added a test to make sure this does not happen again.

You need to specify light or dark. For example,

export BAT_THEME="Solarized (dark)"
