chore: update public suffix list

[maester-bot]

Refreshes powershell/assets/public_domain_suffix_list.dat from the Public Suffix List published at https://publicsuffix.org/list/public_suffix_list.dat.

The Public Suffix List is maintained by Mozilla volunteers and registry submissions. Reviewer background: https://publicsuffix.org/learn/

Why this matters in Maester:

• powershell/public/Get-MtRegistrableDomain.ps1 uses this list to determine the registrable domain boundary.
• powershell/public/maester/entra/Test-MtDomainsDmarcRecordMaturity.ps1 uses that registrable domain to decide which domain should be evaluated for DMARC.

Why some domains are excluded or skipped for DMARC checks:

• The list helps Maester distinguish registry-controlled suffixes from customer-manageable registrable domains.
• That avoids false positives where DMARC would otherwise be evaluated against a public suffix or another non-applicable domain boundary instead of the actual registrable domain.
• Domains such as onmicrosoft.com remain explicitly skipped as not applicable because the tenant does not control the base public suffix used for that shared namespace.

Reviewer note:

• If this list update changes DMARC results, the generated test output already includes the reason in the Reason column, so the impact should be visible in the test result details.
