Inconsistent YAML quoting for numeric strings starting with 0 (08, 09 vs 01-07)

[Skye-flyhigh]

Describe the bug
Keys/values like 08 and 09 lose their quotes when the YAML is
re-serialized, while 01-07 keep them. This is because 08/09
are invalid octals in YAML 1.1.
Result: the translations for the 08 and 09 keys doesn't stay

Extension Version
lokalise.i18n-ally v.2.13.1

Framework/i18n package you are using

• Framework: React (Vite)
• i18n package: react-i18next
• Locale format: YAML (split by namespace)

To Reproduce
Before:

'07': Value
'08': Value
'09': Value

After i18n-ally edits:

  '07': Value
  08: Value    # Lost quotes!
  09: Value    # Lost quotes!

Steps to reproduce the behavior:

1. Open a YAML locale file with keys like '08', '09'
2. Use i18n-ally to translate a string in that file
3. Save the file
4. Observe that '08' and '09' keys lost their quotes

Expected behavior
Numeric string keys like '08' and '09' should retain their quotes
after the file is re-serialized, consistent with '01'-'07'.
