aws-greengrass-component-sdk: recipe filename not renamed during 0.4 -> 1.0.1 upgrade

[rpcme]

Summary

The automated version upgrade PR #15416 updated aws-greengrass-component-sdk from 0.4.0 to 1.0.1, but the recipe filename was not renamed to match.

Current state

• File: recipes-sdk/aws-greengrass-component-sdk/aws-greengrass-component-sdk_0.4.bb
• Contents: PV = "1.0.1" with SRCREV pointing to the 1.0.1 tag

Expected state

• File: recipes-sdk/aws-greengrass-component-sdk/aws-greengrass-component-sdk_1.0.1.bb
• Contents: No explicit PV line needed (version derived from filename)

Impact

The recipe builds correctly due to the explicit PV override, but the filename violates Yocto convention and causes confusion.

Fix

Rename the .bb file to _1.0.1.bb and remove the PV = "1.0.1" line.
