- Optimized/Customized/Catregorize -> Optimised/Customised/Categorise
- Github -> GitHub (80% were spelt with capital H, this is the way GitHub spells itself)
- GitPod -> Gitpod (most were without the capital P, Gitpod's site does not use capital P)
- Remove duplicate words (to to, the the)
- De-coupled -> decoupled
- implementors -> implementers (all other references used 'site implementers' so just aligning with the common case)
- Fix a/an usage in one case
- Fix one comment usage of ok, replace with OK
- Adds a new first contribution guide page
- Refines the contributing index to add more ways to get involved & cleans up that section
- Moves the committing TOC link to the bottom of the contributing index page as this is only needed for core team
- Fixes#10070
