Release v0.17.6 (#119)

* ci: simplify (#117)

* ci: simplify matrix strategy

* ci: create new job running exclusively on `main` updates + make existing full CI test job run only on non-`main` branch PRs

* chore: bump version refs to `0.17.6`

* test: minor improvements to the `ContinuedFraction` unit test for rational operations

* refactor: minor code quality improvements in the `ContinuedFraction` class

* refactor: minor code quality improvements in the `sequences.coprime_pairs_generator` func

* chore(deps): update dev. and docs dependencies

* ci: reset changes in `4d60ae8f2`
