In `@administration/configuring-fluent-bit/yaml/service-section.md`:
- Line 12: Update the dns.resolver description to replace “the plugin making it”
with “the plugin making the connection,” leaving the rest of the resolver
behavior and wording unchanged.
In `@administration/networking.md`:
- Line 43: Update the default resolver-selection sentence to use consistent
terminology: asynchronous plugins use the asynchronous resolver, while
synchronous plugins use the operating system resolver. Keep the surrounding
explanation unchanged.

In `@administration/networking.md`:
- Line 43: Update the resolver-selection documentation to state that mode-based
defaults apply only when both dns.resolver and net.dns.resolver are unset; when
net.dns.resolver alone is unset, clarify that the global dns.resolver governs
every plugin.

…C behavior
- Add a DNS resolver section to administration/networking.md explaining
ASYNC (non-blocking, event loop) vs LEGACY (blocking system resolver)
- Document that an unset net.dns.resolver follows the plugin's own async
or sync mode, and that net.dns.mode applies only to the async resolver
- Expand the dns.resolver description in the YAML service section table
- Fix net.dns.prefer_ipv4 descriptions in azure_kusto, s3, and
opentelemetry output docs that incorrectly repeated the resolver text
- Correct net.dns.prefer_ipv4/ipv6 defaults to false in s3 and
opentelemetry output docs
- Replace "the plugin making it" with "the plugin making the connection"
in the dns.resolver service key description
- Reword the default resolver-selection sentence in networking.md to use
consistent plugin terminology and drop the repeated adverb
- Clarify that mode-based resolver selection applies only when neither
dns.resolver nor net.dns.resolver is set, and that a plugin inherits
the global dns.resolver when only net.dns.resolver is unset
