Typo in browser connection message

[TRMack]

sdk/src/BuiltInTools/dotnet-watch/Browser/BrowserConnection.cs

Line 26 in 301f9e9

Reporter.Verbose($"Connected to referesh server.");

Unless I'm unfamiliar with the word, I believe this should be "Connected to refresh server." That language is also a bit odd, though I assume it's referring to the source it will use to refresh the page's contents.
