BoM j2 files - NW750SPS25_JAVA_HANA_v0001ms / NW750SPS25_JAVA_HANA_v0002ms

Hey Team - we used these two BoM's and we got an error in the installations phase of the scs instance.

BoMs:

SAP/NW750SPS25_JAVA_HANA_v0001ms/templates/NW750SPS25_JAVA_HANA_v0001ms-scs-inifile-param.j2

SAP/NW750SPS25_JAVA_HANA_v0001ms/templates/NW750SPS25_JAVA_HANA_v0002ms-scs-inifile-param.j2

```

We fixed the issue by setting the value from "scs_hostname" to "sap_scs_hostname".

```

58 # You can specify a virtual host name for the ASCS instance. Leave empty for default.
59 NW_SCS_Instance.scsVirtualHostname = {{ sap_scs_hostname }}

```

We tested this on a test machine and it passed successfully with the change.

Inspect the two named templates, NW750SPS25_JAVA_HANA_v0001ms/templates/NW750SPS25_JAVA_HANA_v0001ms-scs-inifile-param.j2 and NW750SPS25_JAVA_HANA_v0002ms/templates/NW750SPS25_JAVA_HANA_v0002ms-scs-inifile-param.j2, and the bom-template task at deploy/ansible/roles-sap/3.3.1-bom-utility/tasks/bom-template.yaml:71. Re-run the SCS installation or template-processing path; done means both templates generate their .params files without an undefined-variable error.
