SupportedStandards inconsistency

[hal0x2328]

The SupportedStandards directive in the NEP17 example at https://github.com/neo-project/docs/blob/master/docs/en-us/develop/write/nep17.md and https://github.com/neo-project/docs/blob/master/docs/zh-cn/develop/write/nep17.md is written as

[SupportedStandards("NEP17", "NEP10")]

but should be written as

[SupportedStandards("NEP-17", "NEP-10")]

if we want to follow the old NEP-10 standard.

Actually since NEP-10 has been marked obsolete, I've raised this issue in the proposals repo, so that it can be added to NEP-15 to ensure consistency going forward:

neo-project/proposals#139

I saw it's a temporary repo for NEP-17 contract code, we'll fix it soon.
