feat: add option to skip dependency check

[moharifhidayat7]

Problem
In some projects, frameworks include Jest as part of their own testing package. As a result, Jest is not listed in the project's dependencies or devDependencies in the package.json file. This causes the current dependency check in neotest-jest to fail, as it relies on detecting Jest in the package.json to determine if the project has jest installed.

This pull request introduces a new feature to the neotest-jest adapter, allowing users to skip the dependency check for Jest. The most important changes include the addition of a new field to the adapter, modifications to the hasJestDependency function, and updates to the adapter initialization to support the new option.

Changes to support skipping dependency check:

• lua/neotest-jest/init.lua: Added a new field skipDependencyCheck to the adapter's type definition.
• lua/neotest-jest/init.lua: Modified the hasJestDependency function to return true if skipDependencyCheck is set.
• lua/neotest-jest/init.lua: Updated the adapter initialization to set skipDependencyCheck based on the provided options.

Example Usage

require('neotest-jest')({
    skipDependencyCheck = true,
    -- Other options...
})
