Changelog for tasty-golden-2.3.1.2

Changes

Docs: link to an introductory blog post

Fix compatibility with optparse-applicative-0.13

Intercept exceptions thrown by the test, adhering to the new tasty API contract.

Switch from temporary-rc to temporary

Impose a lower bound version constraint on bytestring.

Accepting tests is no longer done by a separate ingredient; instead it is now an option that affects tests themselves.
- --accept used to run only golden tests; now all tests are run, but only golden tests are affected by this option
- when accepting, all the usual options apply (such as -j)
- when accepting, the interace is the same as when running
- defaultMain and acceptingTests are kept for compatibility, but do not do anything and are obsolete
When a golden test file does not exist, it is created automatically, even when --accept is not specified. You'll see a message like
```
  UnboxedTuples:                 OK (0.04s)
    Golden file did not exist; created
```
No longer use lazy IO
- ValueGetter type is gone (replaced by IO)
- Because of that, the type of the primitive goldenTest is changed
- vgReadFile function is gone (replaced by Data.ByteString.readFile)
