blade: Bump rev to fix GLES

[lukaslihotzki]

Based on the work on GLES support of @kvark, only two pieces were missing for usable GLES support:

• gles: set unpack alignment to 1 kvark/blade#125 was upstreamed 2 weeks ago and is contained in the currently referenced zed-industries/blade fork
• gles: implement blending and write masks kvark/blade#126 was upstreamed 17 hours ago and is not contained in the zed-industries fork. As the zed-industries fork was also upstreamed in Remove unwraps from init() kvark/blade#128, we can switch back to mainline blade.

If you don't want to switch back to mainline blade, please integrate kvark/blade#126 to your fork.

Release Notes:

• Fix GLES backend (Broken graphics in gpui with the GLES backend of blade-graphics #9581)
