Add users and teams to dependabot security alert information

[aisgbnok]

Why:

Closes #4760

What's being changed:

Viewing and updating Dependabot alerts:

1. Permissions metadata now includes users and teams that have explicit access.
2. sidebar-dependabot-alerts.md reusable now informs users of the security permission requirement for dependabot alerts and includes a link to Managing security and analysis settings for your repository.

Permissions (BEFORE)

Permissions (AFTER)

sidebar-dependabot-alerts.md (BEFORE)

sidebar-dependabot-alerts.md (AFTER)
