Update docs code blocks chart/kubeapps/readme

[tiffanyfay]

Description of the change

• Removes $ from code commands because it makes copy-pasting easier. Otherwise you have to make sure you skip the $, or you get an error (at least on my mac with zsh).
• Swaps console type to bash type for consistency and also because console is only really useful if you're showing commands to be run and the output to distinguish between them.

Should the two blocks in https://github.com/kubeapps/kubeapps/pull/1645/files#diff-fd1223ba99ae8afb3850192caf05b551L198 be bash also? I didn't put anything since they're errors.

The link doesn't drop me at a specific line, but I assume you mean the ones at:

https://github.com/kubeapps/kubeapps/blob/master/chart/kubeapps/README.md#troubleshooting

then I'm not sure it matters (trying it here in the editor with or without doesn't change the presentation, and not sure it matters semantically for the errors). I'll merge as is :)
