Manually bump versionCode after hotfix integration

See rationale from
#17136,
namely:

> We will pick the values from release/20.7 for now, but will have to
> manually bump versionCode to 1269 (instead of the 1268 that our tooling
> will bump from seeing 1267 in trunk) when we'll do the new beta once
> this PR lands.
> (There's no point in choosing versionCode=1268 or versionCode=1269 in
> advance while resolving this conflict, because our tooling we update it
> based on what's in trunk when we'll run fastlane new_beta_release…)
