Fixes #73

Summary of changes

Updates plain-htmx/plain/htmx/assets/htmx/vendor/src/ext/head-support.js to the official v2 release from bigskysoftware/htmx-extensions / htmx-ext-head-support (2.0.5).

Why

plain-htmx ships htmx core 2.0.4, but previously bundled the htmx 1.x version of head-support.js. On every page load where head-support was enabled, the console fired:

head-support.js:9 WARNING: You are using an htmx 1 extension with htmx 2.0.4.
It is recommended that you move to the version of this extension found on
https://htmx.org/extensions

The v2 extension eliminates the warning and safely checks for xhr before accessing xhr.response on htmx:afterSwap.

Verification

• Tested with plain.testing (plain-htmx/tests): 26/26 tests passed.
• Compared against htmx-ext-head-support@2.0.5 on npm and bigskysoftware/htmx-extensions/src/head-support/head-support.js.
