Update ISSUE_TEMPLATE.md

1. A few people don't know what to do with line 6 (the line I changed). 
See, for example:
https://github.com/anbox/anbox/issues/157
https://github.com/anbox/anbox/issues/159
https://github.com/anbox/anbox/issues/141
https://github.com/anbox/anbox/issues/132


2. Since [anbox system-info] prints the version number, we don't need to ask people to do [anbox version].

3. Changed wordings of the other "section titles".
