Added clang v16 to README and action description #145

I also removed 7, 6, 5, 4, or 3.9. from README.md to keep the same as it is in action.yml. Even though we support these versions, I think most users will not use them.

Since we have supported clang v15 and v14, but the default version of clang is v12, do you think we should also update the default version a little higher? maybe v14?

Older projects may need to stick with what was used when introducing static analysis. This is because the major versions have breaking changes between them. If we do support these versions, then they should stay in the README. Otherwise, it would be misleading or unappealing for those that still use those versions.

I don't really mind what the default is now that the version option is all but required. Perhaps, we should make it a required option to

1. avoid having to keep updating the default
2. ensure user-expected behavior

Although, I guess that would be a breaking change in the action.

Agree. so I should add 7, 6, 5, 4, or 3.9 to action.yml to keep confidence.

We should make it a required option

I don't know how to make it a required option, if the user doesn't input version causing action failed that might not be very nice.

Yes, changing the default value maybe cause a break, so I will leave it alone until the user highly suggests us or we make a major/minor not in patch release.

cpp-linter-action/action.yml

Lines 39 to 42 in a13a448

	version:
	description: "The desired version of the clang tools to use. Accepted options are strings which can be 15, 14, 13, 12, 11, 10, 9, or 8. Defaults to 12."
	required: false
	default: "12"

Its a one line change on our end.
