awesomelist: fix SLH-DSA standard number (FIPS 205, not 204)

B. Gap A — FIPS-205 fix in the awesomelist [VERIFIED — new one-line PR]

PR title: awesomelist: fix SLH-DSA standard number (FIPS 205, not 204)

PR body:

awesomelist/README.md labels SLH-DSA as "FIPS 204", but SLH-DSA is standardised in FIPS 205 (FIPS 204 is
ML-DSA, correctly listed on the line above). The hyperlink on the same line already points to the FIPS 205 PDF,
so only the text label is wrong. QS03 also references "NIST FIPS 205 (SLH-DSA)", so this aligns the awesomelist
with the entries.

Exact change (line 38):

- - [NIST Standard: SLH-DSA](https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.205.pdf) - FIPS 204, Stateless Hash-Based Digital Signature Standard (SLH-DSA).
+ - [NIST Standard: SLH-DSA](https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.205.pdf) - FIPS 205, Stateless Hash-Based Digital Signature Standard (SLH-DSA).
