Go 1.10.x breaks version prompt layout

[spotlightishere]

The introduction of Go 1.10.x gave a second digit to the version number.

bullet-train.zsh/bullet-train.zsh-theme

Line 539 in 06f1d86

prompt_segment $BULLETTRAIN_GO_BG $BULLETTRAIN_GO_FG $BULLETTRAIN_GO_PREFIX" $(go version | grep --colour=never -oE '[[:digit:]].[[:digit:]]')"

only expects one digit as shown below, causing the prompt to newline:

> go version | grep --colour=never -oE '[[:digit:]].[[:digit:]]'
1.1
0.2
