• Added the Akamai store type and configuration to types.go (pkg/store/types.go).
• Included Akamai store kind in the list of valid store kinds and added the corresponding configuration struct in config.go (types/config.go). [1] [2] [3]

Dependency Updates:

• Updated several dependencies in go.mod to their latest versions, including golang.org/x/tools, golang.org/x/oauth2, and github.com/linode/linodego (go.mod). [1] [2] [3] [4]

Documentation:

• Added documentation for the Akamai store, including usage instructions and configuration examples (docs/stores/akamai/akamai.md).
