Update dependence on built_value

[rayk]

Current depends on 5.1.0

Built-Value was bumped to 6.0.0 to support new source gen. release not here, note the header config on the build is not longer honoured.

I believe that this issue and #153 are preventing me from building the site-webdev template-syntax example.

Because no versions of code_builder match >3.1.2 <3.1.3 and code_builder >=0.1.3 <3.1.2 requires SDK version >=1.9.1 <2.0.0-∞, code_builder >=0.1.3 <3.1.2-∞ or >3.1.2 <3.1.3-∞ is forbidden.
And because code_builder >=3.1.3 depends on built_value ^6.0.0, code_builder >=0.1.3 <3.1.2-∞ or >3.1.2 requires built_value ^6.0.0.
Because no versions of pageloader match >3.0.1 <4.0.0 and pageloader 3.0.1 depends on built_value ^5.1.0, pageloader ^3.0.1 requires built_value ^5.1.0.
Thus, pageloader ^3.0.1 is incompatible with code_builder >=0.1.3 <3.1.2-∞ or >3.1.2.
And because build_runner >=0.9.1+1 depends on code_builder >2.3.0 <4.0.0 and code_builder 3.1.2 depends on built_collection >=1.0.0 <4.0.0, if pageloader ^3.0.1 and build_runner >=0.9.1+1 then built_collection >=1.0.0 <4.0.0.
And because template_syntax depends on angular_components ^0.10.0 which depends on built_collection ^4.0.0, pageloader ^3.0.1 is incompatible with build_runner >=0.9.1+1.
So, because template_syntax depends on both pageloader ^3.0.1 and build_runner >=0.10.0 <2.0.0, version solving failed.
exit code 1
