Update FSC to 29.0 (#386)

### update FSC to 29.0

update FSC to v29.0

Notes about tests changes:

in `MultipleUnsavedFiles` integration test the error hint `addTwo2` should be valid suggestion
need to check if is a FCS regression or in FSAC

the `Test1Json` integration test it's now flaky (disabled it), the `Range` sometimes finish at start of next line other times at end of current line

like

```diff
        "Range": {
          "StartColumn": 1,
          "StartLine": 1,
-         "EndColumn": 1,
-         "EndLine": 16
+         "EndColumn": 6,
+         "EndLine": 15
        },
```


### update FSharpLint.Core

update FSharpLint.Core to v0.12.1 

support fsharplint xml and json configs

workaround fsharplint message change.
The message format returned by linter is `FS01234: info text"` , so need to strip the warning code from output message

NOTE in the test `LinterWithOptions` the xmlconfig is read and converted, but hints are not disabled.
Changed the test, based on current fsharplint behaviour
