Fix: Update package.json version to match git tag v3.53.0

[jeandoBet]

Summary

The current package.json contains version 3.40.1 while the git repository has tag v3.53.0. This creates inconsistency when installing via npm from git reference:

npm install git+https://github.com/oss-serverless/serverless.git#v3.53.0

Despite specifying tag v3.53.0, npm installs version 3.40.1 because it reads the version from package.json, not from the git tag.

Solution

Update the version field in package.json from 3.40.1 to 3.53.0 to match the git tag.

Impact

• ✅ Fixes version inconsistency between git tags and package.json
• ✅ Ensures npm installations reflect the correct version
• ✅ Improves user experience when installing from git references
• ✅ Maintains compatibility with existing workflows

Verification

After this change, npx serverless --version will correctly display:

osls version: 3.53.0 (local)

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

I'd rather just delete the version out of here if we can.

[jeandoBet]

It seems to be a mandatory field for npm.

Let's find another approach because we don't want to manually update this field.
