Minor fixes to Chapter 1

[dpshelio]

Besides those small fixes, I wonder whether before challenge 2 is worth either explaining the syntax of the tests or rather convert it as pseudo-code like challenge 1.

One way to avoid either of those two steps is to fence the code that needs "attention" on the exercise (either with comments or in the readme pointing to the lines of code where the function needs to be modified), so the learners can focus their attention on the bits that matter and not in veggie syntax.

Pull Request Overview

This PR applies minor fixes to Chapter 1 of the unit-testing tutorial, improving formatting, spelling, and link references.

• Reformatted blockquote and added a proper citation link
• Standardized pseudo-code syntax and fixed a spelling mistake
• Corrected repository paths for Challenge 2 links

Comments suppressed due to low confidence (2)

episodes/1-intro-to-unit-tests.md:123

• The path segment 1-into-to-unit-tests appears to be a typo; it should match the directory name 1-intro-to-unit-tests.

Take a look at [1-into-to-unit-tests/challenge-2](https://github.com/UCL-ARC/fortran-unit-testing-exercises/tree/main/episodes/1-into-to-unit-tests/challenge-2) in the exercises repository.

episodes/1-intro-to-unit-tests.md:127

• The path in the link uses 1-into-to-unit-tests; update it to 1-intro-to-unit-tests to avoid a broken link.

A solution is provided in [episodes/1-into-to-unit-tests/challenge-2/test/solution](https://github.com/UCL-ARC/fortran-unit-testing-exercises/tree/main/episodes/1-into-to-unit-tests/challenge-2/test/solution).
