Improve fuels init directory detection

[petertonysmith94]

Summary

Improve fuels init directory detection, such that, when using the glob pattern for this single program directory:

npx fuels init --predicates ./predicate/* --output ./src/predicate_api

For the following directory structure:

└── predicate
    └── Forc.toml

Actual

We obtain the following fuels.config.ts

import { createConfig } from 'fuels';

export default createConfig({
  predicates: [
        'predicate/Forc.lock',
        'predicate/Forc.toml',
        'predicate/out',
        'predicate/src',
  ],
  output: './src/predicate_api',
});

Expected

We'd expect the following fuels.config.ts

import { createConfig } from 'fuels';

export default createConfig({
  predicates: [
        'predicate'
  ],
  output: './src/predicate_api',
});
