fix: Add DIGEST_MISMATCH

[darkrift]

DIFFERENT_* miss reason were regrouped into a single DIGEST_MISMATCH reason in bazelbuild/bazel@ec10da4

Using Bazel 9.0.0 pre-release results in this crash:

panic: runtime error: index out of range [7] with length 7

goroutine 80 [running]:

[isakstenstrom]

Nice!
From what I can find, the new value would also need to be handled in these files so that the new value would be stored and displayed correctly:

ent/schema/missdetail.go
frontend/src/components/ActionCacheMetrics/ActionCacheMissTag.tsx
frontend/src/components/ActionCacheMetrics/index.module.css

Could you please make the necessary changes in these files as well?

[darkrift]

@isakstenstrom any color preference ? I see you are also modifying them in another PR, I could simply add it in missdetail.go if we merge your other pr first.

[isakstenstrom]

Oh yeah I forgot that those changes would conflict. That sounds good. I don't have any preference for color.

[darkrift]

@isakstenstrom you can also include this change in your other PR if you want. It would be easier to manage that way
