ARROW-18118: [Release][Dev] Fix problems in 02-source.sh/03-binary-submit.sh for 10.0.0-rc0

[kou]

SOURCE_PR in dev/release/02-source.sh didn't work because it refers undefined variable (rc_number is referred not rc). This change includes the following changes including the fix of the undefined variable problem:

• Fix wrong variable use. (Variable name is also changed to adjust other variable names: release_candidate -> rc)
• The ARROW_GITHUB_API_TOKEN environment variable is used for GitHub Personal Access Token but the CROSSBOW_GITHUB_TOKEN environment variable is used in others. So this also uses CROSSBOW_GITHUB_TOKEN. (Documentation is also updated. This change also includes unrelated minor updates. Sorry.)

dev/release/03-binary-submit.sh didn't work because:

• It refers undefined variable (release_candidate_branch).
• archery crossbow report-pr searches only base=master pull requests. (A verify pull request uses base=maint-X.Y.Z.)

This change fixes them. This change also adds --no-fetch to archery crossbow latest-prefix like other command lines to reduce execution time.
