Fix #933. Some files are properly ignored in the LSP too. E.g. package.json, tsconfig.json, etc.
Fix #1394, by inferring the language extension from the internal saved files. Now newly created files JavaScript correctly show diagnostics.

Bug fixes

Linter

Bug fixes

Fix #910, where the rule noSvgWithoutTitle should skip elements that have aria-hidden attributes. Contributed by @vasucp1207

New features

Add useForOf rule. The rule recommends a for-of loop when the loop index is only used to read from an array that is being iterated. Contributed by @victor-teles

Enhancement

Address #924 and #920. noUselessElse now ignores else clauses that follow at least one if statement that doesn't break early. Contributed by @Conaclos

For example, the following code is no longer reported by the rule:
```
function f(x) {
    if (x < 0) {
      // this `if` doesn't break early.
    } else if (x > 0) {
        return x;
    } else {
        // This `else` block was previously reported as useless.
    }
}
```

Bug fixes

Fix #918. useSimpleNumberKeys no longer repports false positive on comments. Contributed by @kalleep

Fix #953. noRedeclare no longer reports type parameters with the same name in different mapped types as redeclarations. Contributed by @Conaclos

Fix #608. useExhaustiveDependencies no longer repports missing dependencies for React hooks without dependency array. Contributed by @kalleep
