docs: remove shell prompts from command blocks

[Ava-91]

Description

Removes the unnecessary leading $ shell prompts from command blocks throughout the documentation.

These prompts are especially annoying in click-to-copy blocks because the $ can be copied as part of the command.

Changes

• Removed leading $ prompts from command examples in:

  • README.md
  • docs/development/local-development.md
  • docs/development/olm-development.md
  • docs/development/releasing.md

• Preserved actual shell variable syntax such as $version and ${...}.

Closes #295
