[JS] fix: ME Auth card title is a fixed string (#1444)

## Linked issues

closes: #1445  (issue number)

## Details

Provide a list of your changes here. If you are fixing a bug, please
provide steps to reproduce the bug.

#### Change details
* Updating `MessageExtensionAuthenticationBase` class to take in "title"
and "text" paramters in it's constructor which it then uses to populate
the auth invoke response. If not provided, it uses default hardcoded
strings.
* I've only updated this for `OAuthMessageExtensionAuthentication` as
the `TeamsSsoMessageExtensionAuthentication` settings (TeamsSsoSetting)
does not currently support `title` and `text` properties.

**screenshots**:

I tested it in the ME OAuth bot and the title updated correctly. The
text however did not, it is most likely a frontend issue. I've reached
out to them about it.
