[Issue#3] add tools for static code analysis - Prettier init config

[KarolinaZakrzewska]

Partially Resolves #3

Scope of changes

• Prettier is set as the default formatting
• formatting of all files corrected
• added Prettier to recommended extensions
  Configurations:
• added the use of single quotes (') in Prettier configuration
• added the use of semicolons (;) at the end of statements in Prettier configuration
• added appropriate line break depending on the system, for Windows: CRLF (\r\n)

How to use

• install Prettier

npm install --save-dev --save-exact prettier

• add an exclusion file .prettierignore

package-lock.json
playwright-report

• add the rules file .prettierrc.json

{
  "singleQuote": true,
  "endOfLine": "auto",
  "semi": true
}

• run Prettier formatting

npx prettier --write .

Additionally, you can add the VSC extension: Prettier - Code formatter (you see it in extensions as recommended)

• set as default formatting
  Right-click in the file e.g. package.json -> Format Document With... -> Configure Default Formatter... -> Select Prettier

I resolved the feature branch conflicts with main. I added create-token.helper.ts to Priettier's ignored list - I'm not sure about its configuration, so I'll add an issue (after merging these changes).
