Restrict error message length

### Description

We should truncate error message to readable size, so that users would only see start of error message, if its large, which is usually the most useful part of long error message.

When resolving the issue, it also worth to pay extra attention to code snippets, where error message is also shown:

### Reproduction steps

- Build up new project using "npm init testplane@latest my-project"
- Modify generated test so it would produce extra long error message
- This error message is shown fully in console and in html-report

Test with long error message example:
```ts
describe("test", () => {
it("example", async () => {
throw new Error("1234567890".repeat(1000));
});
});
```

Error message is truncated to reasonable size. Users can configure maximum error length from config.
