Add context when rendering labels or emojis (go-gitea#23281)
This branch continues the work of go-gitea#23092 and attempts to rid the codebase of any `nil` contexts when using a `RenderContext`. Anything that renders markdown or does post processing may call `markup.sha1CurrentPatternProcessor()`, and this runs `git.OpenRepository()`, which needs a context. It will panic if the context is `nil`. This branch attempts to _always_ include a context when creating a `RenderContext` to prevent future crashes. Co-authored-by: Kyle D <[email protected]>
