Different naming of Golang standard library between trivy and cyclonedx-gomod

### Description
When running trivy and cyclonedx-gomod to generate SBOMs different names for the golang standard libraray component are assigned. This makes merging of SBOMs only possible with a hard coded list of alternative names.

### Desired Behavior
Both trivy and cyclonedx-gomod assign the same name for the golang standard library **stdlib** to allow proper merging of SBOMs. Trivy uses the same identifier as the Go team does for vulnerabilities, e,g [check](https://github.com/golang/vulndb/blob/953c816d6fd6982a83defdb9d886092aafa37e57/data/osv/GO-2023-1621.json#L14).

### Actual Behavior
The golang standard library is named as follows:

trivy: stdlib

``` json
{
"bom-ref": "pkg:golang/stdlib@1.23.4",
"type": "library",
"name": "stdlib",
"version": "1.23.4",
"purl": "pkg:golang/stdlib@1.23.4",
"properties": [
{
"name": "aquasecurity:trivy:LayerDiffID",
"value": "sha256:f75706aada560f9fc3c035a44e9c8f8da8bf7317a39df18ae86c56fdd8344d66"
},
{
"name": "aquasecurity:trivy:LayerDigest",
"value": "sha256:9f888a47f0b0f4ecd36abfd90d4a77bc93fcedb6135f4d24fd36b6d6b232533c"
},
{
"name": "aquasecurity:trivy:PkgType",
"value": "gobinary"
}
]
},
```
cyclonedx-gomod: std

``` json
{
"bom-ref": "pkg:golang/std@go1.23.4?type=module",
"type": "library",
"name": "std",
"version": "go1.23.4",
"scope": "required",
"purl": "pkg:golang/std@go1.23.4?type=module\u0026goos=linux\u0026goarch=amd64"
},
```

### Reproduction Steps
Create SBOM from trivy source code (v0.59.0)
1. cyclonedx-gomod app -json -output cdx.sbom.json -std -main cmd/trivy
2. trivy image --format cyclonedx --output trivy.sbom.json aquasec/trivy:0.59.0

Start by running the two reproduction commands against trivy 0.59.0 and compare the generated CycloneDX components for the Go standard library. Trace where cyclonedx-gomod assigns the standard-library module name and version, then verify the generated component uses stdlib consistently with Trivy and the Go vulnerability database identifier.
