Maintain/update CI: Conan2, CodeCov upload script, dead links

[martukas]

Description

General CI update that ensure all builds and tests pass.

• gui project updated to use Conan v.2, seeing as Conan v1.6 is now deprecated and many packages are not updated for it
• using the new Codecov coverage uploader utility directly from CircleCI orbs.
• common, controller and gui build scripts updated to no longer use codecov-cli utility but instead assume external tool is used.
• A number of links to google docs updated to pass link checker
• A number of google docs had access settings updated to allow public viewer access
• Raspberry pi links excluded from link checker, as their server appears to block the crawler

Self-review checklist:

• Self-review: looked through the Files changed tab, browsed repository in branch
• Documentation updated - reflects changes in code, electrical or mechanical design
• Documentation and graphics follow the documentation style guide
• New content is linked, easily discoverable, does not require too many clicks
• Follows other relevant parts of contributor wiki
• PR has a descriptive name
• Tagged relevant reviewers

Software only:

• Follows our code style
• Commented code, particularly in hard-to-understand areas
• [ ] All tests pass - new and old, locally and on CI
  • Tests passing on CI and locally
  • Do not have a ventilator to deploy and test with hardware, so no integration tests performed
• [ ] No new warnings or static check failures
  • static checks fail, but they were failing before anyways, they were never enabled on CI
• Tests that prove fix is effective or new feature works
• Manual tests are explained, with instructions for reproducing them

Not checked on a PROTOTYPE either but most changes do not affect THE final executables.
LGTM.
