chore: update dependencies in /docs (#2103)

This pull request includes updates to the documentation build process
and dependency management for the project. The most important changes
include switching from `npm` to `yarn` for installing dependencies and
starting the development server, and updating the `mintlify` package
version.

Documentation build process updates:

*
[`docs/README.md`](diffhunk://#diff-0b5ca119d2be595aa307d34512d9679e49186307ef94201e4b3dfa079aa89938L15-R16):
Changed the instructions to use `yarn install` and `yarn dev` instead of
`npm i -g mintlify` and `mintlify dev`.

Dependency management updates:

*
[`docs/package.json`](diffhunk://#diff-adfa337ce44dc2902621da20152a048dac41878cf3716dfc4cc56d03aa212a56L11-R12):
Updated the `mintlify` package version from `^4.0.135` to `^4.0.301` and
moved it from `devDependencies` to `dependencies`. Removed the `sharp`
package from `dependencies`.
